Why Choose the Finder 66.22.9.024.0301 Industrial Power Relay?

The Finder 66.22.9.024.0301 is a high-capacity 30 A, 2-pole normally open (DPST-NO) industrial power relay designed for demanding electrical switching applications. Part of the established Finder 66 Series, it combines robust electromechanical operation with a practical printed circuit board mounting arrangement for industrial automation, electrical equipment and machinery control systems.

Featuring a 24 V DC operating coil and two normally open contacts, the relay enables two separate electrical circuits to be switched simultaneously using a single control signal. The 0301 variant belongs to Finder's two-pole normally open configuration, making it suitable for applications requiring high-current switching without normally closed contact connections.

The Finder 66.22.9.024.0301 is designed for through-hole PCB mounting with bifurcated terminals, allowing direct integration into suitably designed electronic control assemblies. Its reinforced insulation between the coil and contacts, combined with the Finder 66 Series power relay construction, makes it a practical choice for industrial control equipment requiring dependable switching and electrical separation.

Key Advantages

  • High-capacity 30 A industrial power relay for demanding electrical switching applications.
  • Two normally open contacts (DPST-NO) enable simultaneous control of two separate circuits.
  • 24 V DC operating coil for compatible industrial DC control systems.
  • 250 V AC rated contact voltage for appropriately rated electrical loads.
  • 440 V AC maximum switching voltage within the applicable manufacturer ratings.
  • Reinforced coil-to-contact insulation for enhanced electrical separation.
  • 8 mm creepage and clearance distances between the coil and contacts.
  • Through-hole PCB mounting for direct integration into electronic equipment.
  • Bifurcated PCB terminals provide a practical connection arrangement.
  • Monostable operation automatically opens the contacts when the coil is de-energised.

Key Features

  • Finder 66 Series industrial power relay.
  • 2 NO (DPST-NO) contact configuration.
  • Two normally open contact sets operated by a common electromagnetic coil.
  • 30 A rated normally open contacts for suitable resistive AC loads.
  • 24 V DC nominal coil voltage.
  • 1.7 W nominal DC coil consumption.
  • 250 V AC rated contact voltage.
  • 440 V AC maximum switching voltage.
  • 7,500 VA rated AC-1 load for normally open contacts.
  • Electromagnetic, non-latching switching mechanism.
  • Reinforced insulation between coil and contacts.
  • 8 mm coil-to-contact creepage and clearance distances.
  • Through-hole PCB mounting with bifurcated solder terminals.
  • Suitable for high-current switching in industrial electronic assemblies.

Reliable High-Current Switching with 24 V DC Control

The Finder 66.22.9.024.0301 operates using an electromagnetic coil to control two mechanically linked normally open contacts. When the 24 V DC coil is energised, both contact sets close and allow current to flow through their respective load circuits. When coil power is removed, the contacts automatically return to their normally open positions.

The 30 A normally open contact rating makes this relay suitable for demanding electrical switching applications where a relatively low-voltage control circuit must operate higher-current loads. Its two-pole arrangement allows two circuits to respond to the same control signal, while reinforced insulation helps maintain electrical separation between the control coil and the switched contact circuits.

Designed for direct PCB mounting, the Finder 66.22.9.024.0301 is particularly useful in industrial electronic assemblies and OEM equipment. Circuit board copper tracks, solder connections, protective devices and thermal management must be suitable for the intended current. The full manufacturer part number should also be checked when selecting a replacement, as different Finder 66 Series variants can have different contact arrangements and terminal configurations.

Typical Applications

  • Industrial automation and machinery control systems.
  • High-current electrical switching assemblies.
  • PCB-based industrial control equipment.
  • 24 V DC control and power-switching interfaces.
  • Industrial heating and resistive load switching.
  • Electrical power distribution and load control.
  • Motor control and auxiliary electrical circuits.
  • Building automation and electrical management systems.
  • Industrial lighting and electrical equipment control.
  • Power supply and equipment switching assemblies.
  • Manufacturing machinery and OEM electronic equipment.
  • Maintenance of compatible Finder 66 Series relay installations.

Frequently Asked Questions

What is the Finder 66.22.9.024.0301 used for?

The Finder 66.22.9.024.0301 is an industrial electromechanical power relay designed for switching electrical circuits in automation systems, machinery control equipment and PCB-based electronic assemblies. Its two normally open contacts allow two circuits to be switched simultaneously using a single control signal.

What coil voltage does the Finder 66.22.9.024.0301 require?

The relay uses a 24 V DC coil with a nominal power consumption of 1.7 W. It is intended for appropriately rated direct-current control circuits and should not be connected directly to an AC coil supply.

What is the contact rating of the Finder 66.22.9.024.0301?

The Finder 66.22.9.024.0301 belongs to the 30 A Finder 66 Series power relay range. Its normally open contacts have a rated voltage of 250 V AC and a maximum switching voltage of 440 V AC. Permissible switching current depends on the load characteristics and operating conditions.

What does the DPST-NO contact configuration mean?

DPST-NO stands for double-pole single-throw, normally open. The relay contains two normally open contact sets that close when the electromagnetic coil is energised and return to their open positions when the coil is de-energised. This arrangement does not provide normally closed switching contacts.

How is the Finder 66.22.9.024.0301 mounted?

The relay is designed for through-hole PCB mounting using bifurcated solder terminals. It is installed directly onto a suitably designed printed circuit board rather than into a conventional plug-in relay socket. The PCB layout and electrical connections must be rated for the intended load.

What should be checked when replacing the Finder 66.22.9.024.0301?

When selecting a replacement, verify the complete manufacturer part number, 24 V DC coil, two normally open contacts, contact ratings, PCB footprint, terminal arrangement and variant-specific characteristics. A similar Finder 66 Series relay may not be electrically or mechanically interchangeable.
