Finder 093.20.1 – 93 Series Sockets for 34 Series relays – Accessory

Why Choose the Finder 093.20.1 Red 20-Way Jumper Link?

The Finder 093.20.1 is a genuine red 20-way jumper link designed for compatible Finder Series 38 relay interface modules. Part of Finder's Series 93 accessory range, this electrical bridging accessory provides a practical method of distributing a common electrical connection across multiple compatible relay interface terminals.

Designed for use with Finder 38.21, 38.51, 38.61, 38.81 and 38.91 interface modules, the 093.20.1 allows installers to connect up to 20 adjacent positions using a single purpose-designed jumper strip. This helps simplify control panel wiring, reduce the number of individual bridging conductors and maintain a neat, organised installation.

The jumper link has a manufacturer's specified maximum capacity of 36 A at 250 V. Importantly, Finder states that each individual pole must not exceed the 6 A limit of the relay interface to which it is connected. The overall jumper rating must therefore be considered alongside the ratings of the connected modules and the complete electrical circuit.

Finished in red, the Finder 093.20.1 offers a useful visual identification option for control panel builders who wish to distinguish different common connections or wiring groups. Alternative versions are available in blue and black.

Identified by manufacturer part number 093.20.1, this accessory is intended for professional electrical control, industrial automation and relay interface installations. It is a passive electrical connection accessory, not a relay, fuse, protective device or standalone switching component.

20-Way Electrical Bridging for Finder Series 38 Relay Interfaces

The Finder 093.20.1 provides a dedicated method of connecting common electrical terminals across a group of compatible relay interface modules.

In many industrial control panels, several relay interfaces are installed next to one another to provide electrical isolation, signal switching or interfacing between control equipment and external loads.

These relay interfaces may require a common supply or other shared electrical connection. Without a suitable bridging accessory, installers may need to connect the modules using individual wires and terminal links.

The Finder 093.20.1 red jumper strip offers a more organised alternative by providing up to 20 connection positions in a single component.

This can simplify panel assembly and help reduce the number of individual conductors required for common connections. It can also improve the visual consistency of a multi-relay installation.

The jumper is designed specifically for compatible Finder interface terminals. It should not be treated as a universal terminal block bridge or assumed to fit unrelated relay sockets.

The correct terminals and connection arrangement must be confirmed from the relevant Finder Series 38 installation documentation before fitting the jumper.

Compatibility with Finder 38.21, 38.51, 38.61, 38.81 and 38.91

Finder specifies the 093.20 series 20-way jumper links for use with the following relay interface types:

• Finder 38.21 relay interface modules.
• Finder 38.51 relay interface modules.
• Finder 38.61 relay interface modules.
• Finder 38.81 relay interface modules.
• Finder 38.91 relay interface modules.

These compatible interfaces form part of Finder's Series 38 range, which is used in industrial automation and electrical control systems.

The 6.2 mm pitch of the jumper corresponds to the intended arrangement of compatible interface modules.

Not every Finder Series 38 interface uses the same jumper design. In particular, other Series 38 types are associated with the separate Finder 093.08 eight-way jumper range.

The full interface part number should therefore be checked before selecting the Finder 093.20.1.

Understanding the 36A Jumper Rating and 6A Individual Pole Limit

One of the most important technical characteristics of the Finder 093.20.1 is its specified electrical capacity.

Finder identifies the 20-way jumper link with rated values of 36 A and 250 V.

However, this does not mean that every connected relay interface can carry 36 A. Finder explicitly states that each individual pole must not exceed the 6 A limit of the interface to which it is connected.

The 36 A figure describes the maximum capacity of the jumper link, while the 6 A limit applies to each individual connected interface pole.

When designing a common electrical connection, the current distribution across the jumper and the ratings of all connected modules must be considered.

The total current, individual branch currents, supply protection, conductor ratings and connected equipment must remain within the relevant electrical specifications.

The jumper link does not provide overload protection or short-circuit protection. Suitable circuit protection must be provided separately as required by the installation design.

Red Colour for Clear Control Panel Identification

The Finder 093.20.1 is supplied in red, distinguishing it from the blue and black versions in the same jumper family.

Colour differentiation can be useful in control panels containing several groups of relay interfaces or different common electrical connections.

For example, a panel builder may choose different jumper colours to support an established internal wiring identification scheme.

However, the colour of the jumper should not be treated as an automatic indication of voltage, polarity or electrical function. The meaning of any colour arrangement must be defined by the installation's wiring documentation and applicable electrical standards.

The Finder 093.20.1 has the same general product function as the other colour variants, but its red finish provides an additional visual identification option.

Finder 093.20 vs 093.20.0 vs 093.20.1

Finder provides three colour variants of its 20-way Series 93 jumper link.

Part Number	Colour	Number of Ways	Rated Values
Finder 093.20	Blue	20	36 A / 250 V
Finder 093.20.0	Black	20	36 A / 250 V
Finder 093.20.1	Red	20	36 A / 250 V

All three variants are associated with the same specified Finder Series 38 interface types, with a maximum individual interface pole current of 6 A.

The main difference is the jumper colour, allowing installers to select the version most appropriate for their control panel identification requirements.

Finder 093.20.1 vs Finder 093.08.1 – What's the Difference?

The Finder 093.20.1 and Finder 093.08.1 are both red jumper links, but they are designed for different relay interface configurations.

Feature	Finder 093.20.1	Finder 093.08.1
Colour	Red	Red
Number of ways	20	8
Maximum jumper current	36 A	10 A
Rated voltage	250 V	250 V
Compatible interfaces	38.21 / 38.51 / 38.61 / 38.81 / 38.91	38.01 / 38.11 / 38.31 / 38.41 / 38.52 / 38.62
Primary function	20-position bridging	8-position bridging

The two jumper families are not automatically interchangeable. They differ in connection arrangement, number of positions and electrical capacity.

The correct jumper should always be selected according to the full Finder relay interface reference.

Using the Finder 093.01 Plastic Separator

Finder also offers the 093.01 plastic separator for compatible relay interface assemblies.

The separator has a specified thickness of 2 mm and is used at the start and end of a group of interfaces.

Finder identifies the separator as particularly important for protective separation between neighbouring PLC interfaces operating at different voltages, according to the relevant installation requirements.

It is also specified for protection of cut jumper links.

Where a jumper strip is shortened or where adjacent interface groups operate at different voltages, the manufacturer's separator requirements must be followed.

The jumper link alone should not be relied upon to provide the required protective separation between different electrical circuits.

Installation Considerations for Relay Interface Jumper Links

Before installing the Finder 093.20.1, verify that the relay interface modules are compatible with the 20-way jumper arrangement.

The interfaces should be correctly mounted and aligned so that the jumper can engage with the intended connection terminals without excessive mechanical force.

The correct common connection must be identified from the wiring diagram. The jumper should only bridge terminals intended to be electrically common.

Particular care is required where different voltages, separate supply circuits or independently protected circuits are present within the same control panel.

If the jumper is shortened for a smaller group of interfaces, any exposed ends must be addressed in accordance with Finder's instructions, including the use of suitable separators where specified.

The electrical load must remain within the 36 A maximum jumper capacity and the 6 A per-pole interface limit, as well as any lower limits imposed by connected equipment.

Installation and maintenance should be carried out by appropriately qualified personnel with the relevant electrical circuits safely isolated.
