Why Choose the Finder 56.34.8.400.0010 Miniature Power Relay?

The Finder 56.34.8.400.0010 is a high-performance 12 A miniature electromechanical power relay designed for industrial automation, machinery control and electrical switching applications. Part of the established Finder 56 Series, this four-pole relay combines dependable switching performance with a convenient plug-in construction, making it suitable for industrial control panels and electrical equipment.

Featuring a 400 V AC operating coil and four changeover contacts (4 CO / 4PDT), the Finder 56.34.8.400.0010 enables multiple independent electrical circuits to be controlled simultaneously using a single electromagnetic coil. Its silver nickel (AgNi) contacts provide reliable switching performance for appropriately rated resistive and inductive loads.

With a 12 A rated contact current, 250 V AC rated switching voltage and 3,000 VA AC1 resistive switching capacity, this relay is suitable for a wide range of industrial control duties. Its plug-in terminal arrangement allows installation into compatible Finder 96 Series relay sockets, simplifying replacement, servicing and electrical panel maintenance.

Four-Pole Switching for Industrial Automation and Control Systems

The Finder 56.34.8.400.0010 operates using an electromagnetic coil that controls four mechanically linked changeover contacts. When the specified 400 V AC control voltage is applied, the relay energises and transfers each common contact from its normally closed terminal to its normally open terminal. When the coil supply is removed, the contacts return to their original positions.

The 4 CO / 4PDT contact arrangement provides four separate changeover circuits operated by a common coil. This allows the relay to perform multiple control functions simultaneously, such as switching auxiliary equipment, distributing control signals or providing electrical status indications.

The relay's 12 A contact rating makes it suitable for a range of industrial switching applications, subject to the electrical characteristics of the connected loads. Its AgNi contact material offers dependable performance for conventional control duties, while the plug-in design supports straightforward maintenance and replacement.

Installation into a compatible Finder 96 Series socket provides a practical interface between the relay and the electrical panel wiring. Where DIN rail mounting is required, a suitable socket can be mounted onto a standard 35 mm DIN rail. The relay itself is a plug-in component and requires the appropriate mounting arrangement.

The 400 V AC coil supply must be distinguished from the contact switching voltage. The coil is designed for a compatible 400 V AC control circuit, while the contacts have a rated switching voltage of 250 V AC. The maximum switching voltage of 400 V AC must not be treated as the continuous rated switching voltage. Appropriate circuit protection, insulation and load selection are essential.

Typical Applications

  • Industrial automation and machinery control.
  • Electrical control panels and switchgear assemblies.
  • Multi-circuit control and auxiliary switching.
  • Industrial motor control circuits within rated limits.
  • Production machinery and manufacturing equipment.
  • Electrical signal distribution and control interfacing.
  • Building management and HVAC control systems.
  • Industrial ovens and process equipment.
  • OEM electrical equipment and automation assemblies.
  • Maintenance and replacement of compatible four-pole industrial relays.

Frequently Asked Questions

What is the Finder 56.34.8.400.0010 used for?

The Finder 56.34.8.400.0010 is a four-pole miniature electromechanical power relay used for industrial automation, machinery control and electrical switching. It provides four changeover contacts, each with a rated current of 12 A.

What coil voltage does the Finder 56.34.8.400.0010 require?

The relay uses a 400 V AC nominal operating coil designed for 50/60 Hz supplies. This is the control coil voltage and should not be confused with the relay's rated contact switching voltage of 250 V AC.

What does the 4 CO contact configuration mean?

4 CO means four changeover contacts, also described as 4PDT. Each pole has a common, normally open and normally closed connection. All four poles change state together when the relay coil is energised.

Can the Finder 56.34.8.400.0010 be mounted on a DIN rail?

Yes, when used with an appropriately rated Finder 96 Series DIN rail mounting socket. The relay itself uses a plug-in connection and does not mount directly onto the DIN rail.

What is the difference between the 12 A contact rating and the 20 A peak current rating?

The 12 A rating is the relay's nominal contact current under specified conditions. The 20 A peak rating refers to a short-duration current capability and must not be interpreted as a continuous operating current. The permissible load depends on the switching voltage, load characteristics and manufacturer's operating limits.
