FINDER Miniature Power Relay 12A 3PCO plug in 110VAC 4pole 56.34.8.110.4040
Finder 56.34.8.110.4040 is a 56 Series miniature power relay featuring a 110 V AC coil, four changeover contacts, a 12 A contact rating and plug-in connections for industrial automation and electrical control applications.
Why Choose the Finder 56.34.8.110.4040 Miniature Power Relay?
The Finder 56.34.8.110.4040 is a 12 A miniature power relay from the Finder 56 Series, designed for industrial automation, electrical control panels and machinery switching applications. Featuring a 110 V AC coil and four changeover contacts (4 CO / 4PDT), this relay enables four separate circuits to be switched using a common control signal.
The Finder 56.34 relay configuration provides a versatile solution for multi-circuit control, auxiliary switching, equipment signalling and electrical interlocking. Its 12 A rated contact current and 250 V AC rated contact voltage support appropriately specified industrial loads, while the plug-in design allows installation into compatible relay sockets.
The 56.34.8.110.4040 ordering code identifies a specific version within the Finder 56 Series. The established 56.34 design includes Faston 187 quick-connect terminals and a compact four-pole construction. The precise additional features associated with the 4040 suffix should be confirmed against the manufacturer's exact variant documentation before selection or installation.

Reliable Multi-Circuit Switching for Industrial Automation
The Finder 56.34.8.110.4040 provides electromechanical switching for industrial systems requiring several circuits to respond to one control signal. When the 110 V AC coil is energised, the four changeover contacts transfer from their normally closed positions to their normally open positions. This arrangement supports coordinated switching, electrical interlocking, equipment signalling and auxiliary control functions.
Its four-pole configuration is useful in control panels where multiple relay outputs are required but available installation space is limited. The plug-in design also supports convenient servicing when used with a correctly specified socket. For inductive loads, motors or circuits with high inrush currents, engineers should select the relay using the relevant load-specific switching ratings rather than the AC1 resistive-load rating alone.
Typical Applications
- Industrial automation and machinery control panels.
- 110 V AC auxiliary control circuits.
- PLC interface and relay-based switching systems.
- Multi-circuit electrical interlocking.
- Equipment signalling and status indication.
- Building automation control equipment.
- Heating, ventilation and air conditioning control panels.
- Production machinery and process control systems.
- OEM electrical equipment and control cabinets.
- Maintenance and replacement of compatible Finder 56 Series relays.
- Applications requiring four changeover contacts.
