Why Choose the Finder 46.61.8.240.0040 Miniature Industrial Relay?
The Finder 46.61.8.240.0040 is a high-quality 16 A miniature industrial electromechanical relay designed for dependable electrical switching in industrial automation, control panels, machinery and electrical distribution equipment. Part of the established Finder 46 Series, this relay combines a 240 V AC electromagnetic coil, a single changeover contact and practical maintenance features in a compact, socket-mountable design.
Featuring a single-pole double-throw (SPDT / 1 CO) contact configuration, the Finder 46.61.8.240.0040 provides both normally open and normally closed switching functions. Its 16 A rated contact current, 250 V AC rated contact voltage and 440 V AC maximum switching voltage make it suitable for a wide range of appropriately rated industrial loads and auxiliary control circuits.
This particular .0040 variant includes a lockable test button and mechanical indicator, making it especially useful for electrical panel commissioning, troubleshooting and routine maintenance. Its silver nickel (AgNi) contacts, Faston 187 quick-connect terminals and compatibility with suitable Finder relay sockets provide a practical solution for electrical engineers, maintenance technicians and OEM equipment manufacturers.

The Finder 46.61.8.240.0040 operates through a 240 V AC electromagnetic coil that controls a single changeover contact. When the coil is energised, the common contact transfers from the normally closed terminal to the normally open terminal. When coil power is removed, the contact returns to its original position. This provides a practical method for changing circuit states, operating auxiliary loads and implementing control functions in industrial equipment.
A distinguishing feature of the .0040 configuration is its lockable test button, which allows authorised personnel to manually operate the relay during controlled commissioning and maintenance procedures. The integrated mechanical indicator also makes it easier to check the relay's operating position. These features are valuable in control cabinets where technicians need to identify and test individual switching circuits. Manual testing must only be performed where it is safe to energise the connected equipment, and the test button should not be used as a substitute for electrical isolation.
The relay's Faston 187 plug-in terminals make it suitable for compatible Finder sockets, including appropriate 97 Series relay bases. Socket mounting can simplify future replacement and reduce maintenance downtime. For reliable operation, engineers should verify the selected socket's current rating, conductor size, wiring arrangement and compatibility with the intended switching load.
