FINDER Miniature Power Relay 12A 3PCO plug in 110VAC 4pole 56.34.8.110.2040.
The Finder 56.34.8.110.2040 is a robust and versatile general-purpose electromechanical power relay designed for electrical switching, industrial automation and machinery control applications. As part of the established Finder 56 Series, this miniature power relay combines high-current switching capability with a compact plug-in design for reliable operation in industrial electrical control panels.
Featuring four changeover contacts (4PDT) with a rated contact current of 12 A, the Finder 56.34.8.110.2040 allows multiple electrical circuits to be switched using a single control signal. Its 110 V AC operating coil is suitable for industrial control installations using 110 V AC auxiliary supplies, including machinery control, electrical interlocking and automation equipment.
The relay incorporates silver cadmium oxide (AgCdO) contacts, a lockable test button and a mechanical position indicator. Its plug-in construction enables straightforward installation and replacement using compatible Finder Series 96 relay sockets, making it a practical choice for machine builders, control panel manufacturers and industrial maintenance engineers.
Industrial power relays such as the Finder 56.34.8.110.2040 provide a dependable method of controlling multiple electrical circuits through a separate AC control supply. When the 110 V AC coil is energised, the relay's electromagnetic mechanism changes the position of its four changeover contacts, allowing connected circuits to be switched according to the requirements of the control system.
The Finder 56 Series is designed for industrial switching applications where reliable contact operation, compact construction and straightforward maintenance are important. Its plug-in design allows installation into compatible relay sockets, simplifying replacement without extensive changes to existing control wiring. The integrated mechanical position indicator and lockable test button provide useful functionality during commissioning, inspection and maintenance.
With four changeover contact sets rated at 12 A, the Finder 56.34.8.110.2040 is suitable for applications requiring several circuits to operate from a common control signal. These include electrical interlocking, industrial signalling, auxiliary motor control and switching of appropriately rated electrical loads. The relay's switching capacity must be evaluated against the load type, operating voltage, inrush current and required switching duty.

The Finder 56.34.8.110.2040 is an industrial electromechanical power relay used for switching multiple electrical control and load circuits in machinery, automation systems and electrical control panels. Its four changeover contacts allow several circuits to be controlled using one AC control signal.
The relay operates using a 110 V AC coil supply at 50/60 Hz. It is designed for alternating-current control circuits and should not be connected directly to a 110 V DC supply.
The relay features four changeover contacts (4PDT), each providing normally open and normally closed switching paths. The contacts have a nominal current rating of 12 A, subject to the connected electrical load and applicable switching conditions.
Yes. The relay includes a lockable test button for manual operation and a mechanical position indicator for visual inspection of relay status. These features assist with commissioning and maintenance. Manual operation should only be performed when it is safe for the connected equipment to operate.
The relay uses a plug-in mounting arrangement and can be installed into a compatible Finder Series 96 socket designed for the four-pole 56.34 configuration. This allows convenient integration into industrial electrical control panels and simplifies relay replacement during maintenance.
Finder 56 Series miniature power relays are used by electrical engineers, automation specialists and machine builders for dependable industrial switching. The Finder 56.34.8.110.2040 combines a 110 V AC coil, four 12 A changeover contacts, silver cadmium oxide contact material, a lockable test button and convenient plug-in installation to provide a versatile solution for industrial control, electrical switching and machinery automation.
