400 A High-Current Power Distribution

The Finder 9D.01.5.400.0111 is designed to distribute electrical power from a main incoming conductor to multiple outgoing circuits.

Its 400 A nominal current rating makes it suitable for appropriately engineered power distribution assemblies where substantial current capacity is required. The block provides a single common electrical connection across its twelve terminals, enabling one supply conductor to feed up to eleven outgoing conductors.

This arrangement can simplify electrical panel construction compared with distributing power through multiple separately connected terminals or improvised conductor junctions.

By incorporating the distribution connections into a purpose-designed component, panel builders can create a more organised wiring arrangement and improve accessibility for inspection and maintenance.

The 400 A rating applies to the distribution block under its specified operating conditions. It does not mean that each outgoing terminal can independently carry 400 A, nor does it permit the combined load to exceed the applicable rating of the block, incoming conductor or upstream protection.

Each outgoing circuit must be designed according to its conductor size, load current, protective device and applicable electrical installation requirements.

One Incoming Connection and Eleven Outgoing Terminals

A defining feature of the Finder 9D.01.5.400.0111 is its 1-in / 11-out connection arrangement.

The incoming terminal is designed to accommodate a comparatively large power conductor, while the eleven outgoing terminals allow that supply to be distributed to several appropriately rated branch circuits.

This makes the block particularly useful in industrial electrical cabinets where a single feeder must supply multiple items of equipment or several separately protected circuits.

Typical downstream equipment may include control transformers, power supplies, drives, contactor circuits, distribution devices and other electrical components, provided the installation is engineered for the relevant current and voltage ratings.

The twelve connection positions are electrically common within the single-pole block. They do not provide separate switching, isolation or overcurrent protection.

Where independent protection is required for individual outgoing circuits, appropriately rated protective devices must be installed as part of the electrical system.

Large Cable Capacity for Industrial Feeder Connections

The Finder 9D.01.5.400.0111 accommodates an incoming conductor cross-section of 95–185 mm², making it suitable for high-current feeder connections in industrial distribution equipment.

The outgoing terminals accommodate smaller conductor sizes, allowing the incoming supply to be divided between multiple circuits with different cable requirements.

The precise outgoing cable capacity depends on the individual terminal position, conductor construction and applicable product approval. The manufacturer's terminal diagram should be consulted before specifying the conductor arrangement.

For the incoming connection, a 25 Nm tightening torque is specified. The correct torque settings for the outgoing terminals are marked on the product cover.

Using the specified tightening torque is important because inadequate tightening may result in increased contact resistance and overheating, while excessive tightening may damage the terminal or conductor.

Conductors must be prepared and installed in accordance with the manufacturer's instructions, including any requirements concerning conductor type, stripping length and terminal capacity.

High-Voltage AC and DC Distribution Capability

The Finder 9D.01.5.400.0111 is suitable for appropriately designed AC and DC power distribution applications.

Its published voltage capabilities include 1,000 V AC and 1,500 V DC, making it relevant to a wide range of industrial electrical systems.

The ability to accommodate high DC voltages can be particularly useful in selected renewable energy and industrial DC distribution applications.

However, the actual permissible operating voltage depends on the applicable certification, installation arrangement, environmental conditions and electrical system design.

The voltage rating of the terminal block does not establish the voltage rating of the complete assembly. Insulation coordination, conductor ratings, protective devices, enclosure design and applicable installation standards must all be considered.

The Finder 9D.01.5.400.0111 is a passive electrical distribution component and does not provide a switching or disconnection function.

35 mm DIN Rail Mounting for Electrical Cabinets

The Finder 9D.01.5.400.0111 is designed for mounting on a standard 35 mm DIN rail in accordance with EN 60715.

DIN rail mounting allows the distribution block to be incorporated into industrial electrical cabinets alongside other appropriately mounted control and power distribution components.

This provides a practical installation arrangement for electrical panel manufacturers and maintenance professionals working with standardised cabinet layouts.

The block's compact construction helps reduce the space required for multiple high-current distribution connections.

Its modular design also supports the arrangement of multiple distribution blocks for suitable multi-pole systems, allowing separate electrical conductors to be distributed through individual blocks.

Where several blocks are installed together, appropriate spacing, insulation coordination and mechanical installation requirements must be observed.

Reversible Snap-On Cover and Identification Markers

The Finder 9D Series incorporates a reversible snap-on cover designed to provide additional protection for the terminal connection area.

The cover also carries useful technical information, including applicable ratings, approvals and tightening torque requirements.

Having this information available directly on the component can assist installers and maintenance technicians when checking electrical connections.

The block is also supplied with an identification marking kit featuring:

• L1 – phase conductor identification.
• L2 – phase conductor identification.
• L3 – phase conductor identification.
• N – neutral conductor identification.
• PE – protective earth identification.
• + – positive DC conductor identification.
• - – negative DC conductor identification.

These markers help panel builders identify the intended electrical function of each distribution block.

The markings do not change the electrical characteristics of the component. The block must be installed and used in accordance with the requirements for the relevant conductor and electrical system.

With an IP10 protection rating, the Finder 9D.01.5.400.0111 is intended for installation within an appropriately designed electrical enclosure. The snap-on cover should not be treated as a substitute for the enclosure's required protection against accidental contact.

Suitable for Selected Solar and DC Power Distribution Applications

Finder identifies the 9D Series as suitable for several distribution configurations, including the grouping of multiple inputs into a common output for appropriate solar applications.

This provides flexibility beyond conventional one-input-to-multiple-output arrangements.

In a suitably engineered DC distribution system, a high-current terminal block can provide a common connection point for conductors that must be electrically joined.

The Finder 9D.01.5.400.0111 offers a high DC voltage capability, making it potentially useful for selected renewable energy installations where the electrical design requires a terminal block of this type.

However, solar photovoltaic systems require particular attention to fault currents, conductor protection, disconnection arrangements and DC-rated equipment.

The Finder 9D.01.5.400.0111 is not a fused combiner, isolator or surge protection device. These functions must be provided separately where required by the installation.

Finder 9D Series Current Ratings Compared

The Finder 9D Series includes several high-current distribution terminal blocks designed for different electrical requirements.

• Finder 9D.01.5.080.0304: 80 A distribution block with seven connections.
• Finder 9D.01.5.125.0206: 125 A distribution block with eight connections.

• Finder 9D.01.5.400.0111: 400 A distribution block with twelve connections.

The Finder 9D.01.5.400.0111 offers the highest nominal current rating within these listed 9D Series variants.

When selecting between models, engineers should consider not only the current rating but also the number of terminals, incoming and outgoing conductor sizes, operating voltage and available installation space.
