46.52.8.240.0040 Finder Miniature industrial relay 2pole 8A 240V

Why Choose the Finder 46.52.8.240.0040 Miniature Industrial Relay?

The Finder 46.52.8.240.0040 is a versatile 8 A miniature industrial electromechanical relay designed for dependable switching in industrial automation, electrical control panels and machinery. Part of the established Finder 46 Series, it combines robust switching performance with practical maintenance features, making it suitable for both new control installations and replacement applications.

Featuring a 240 V AC operating coil and two changeover contacts (2 CO / DPDT), the Finder 46.52.8.240.0040 enables two independent electrical circuits to be switched simultaneously using one control signal. Its silver nickel (AgNi) contacts provide dependable switching for compatible electrical loads, while the built-in lockable test button and mechanical indicator support commissioning, inspection and troubleshooting.

With an 8 A rated contact current, 250 V AC rated contact voltage and compact socket-mountable construction, this relay is well suited to industrial electrical control systems. It can be installed in compatible Finder 97 Series sockets or connected using its quick-connect terminals, providing flexibility for panel builders, maintenance engineers and automation professionals.

Dependable Dual-Circuit Switching with Manual Testing

The Finder 46.52.8.240.0040 uses an electromagnetic mechanism to control two independent changeover contacts. When the 240 V AC coil is energised, both contacts transfer from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts automatically return to their normal states.

The DPDT contact configuration is particularly useful in industrial control circuits requiring coordinated switching, signal routing or auxiliary control functions. Each changeover contact provides common, normally open and normally closed connections, allowing one relay to perform two switching operations from a single AC control signal.

The built-in lockable test button and mechanical indicator provide practical advantages during installation and maintenance. The test facility allows the relay mechanism to be operated manually for appropriate commissioning checks, while the mechanical indicator makes the relay's operating state easier to inspect. Manual testing must be carried out with appropriate electrical safety precautions, particularly where connected machinery could start unexpectedly.
