Why Choose the Finder 62.82.9.012.4040 Power Relay?
The Finder 62.82.9.012.4040 is a 16 A electromagnetic power relay with a 12 V DC operating coil, designed for reliable electrical switching in industrial automation, machinery control and electrical control panels. Part of the established Finder 62 Series, this relay combines two-pole changeover switching, durable contact technology and convenient manual testing features.
Featuring two changeover contacts (2 CO / DPDT), the Finder 62.82.9.012.4040 enables two independent electrical circuits to be controlled simultaneously using a single 12 V DC control signal. Each changeover contact provides normally open and normally closed switching paths, making the relay suitable for equipment interlocking, electrical signalling, control logic and load switching.
The 4040 configuration includes silver tin oxide (AgSnO2) contacts, a lockable test button and a mechanical indicator. These features support practical commissioning, troubleshooting and maintenance. With its 16 A contact rating, 250 V AC rated switching voltage, Faston 250 terminals and rear flange mounting, this relay provides a versatile solution for industrial electrical installations.

Technical note: The Finder 62.82.9.012.4040 is a 12 V DC relay with two changeover contacts, silver tin oxide contact material, a lockable test button and mechanical indicator. The 16 A rating applies under specified switching conditions and must not be assumed for all AC or DC loads. Confirm coil operating limits, load ratings, approvals and installation requirements against Finder's current 62 Series technical documentation before final engineering selection.
Reliable 12 V DC-Controlled Switching with Manual Test Function
The Finder 62.82.9.012.4040 enables two independent electrical circuits to be controlled using a single 12 V DC operating coil. When the coil is energised, the relay's electromagnetic mechanism transfers both changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their original positions during normal operation.
The DPDT contact arrangement provides flexibility for industrial control applications because each contact set can select between two electrical paths. This makes the relay suitable for control logic, equipment interlocking, status signalling and coordinated switching where two circuits must respond to the same control signal.
The lockable test button provides an important commissioning and maintenance feature. In its standard momentary mode, pressing the button mechanically operates the relay contacts, which return when the button is released. Finder's test-button mechanism can also be configured for locking operation by following the manufacturer's instructions.
The mechanical indicator provides a visible indication of relay actuation, helping maintenance personnel check the relay's operating state during inspection and troubleshooting. Unlike versions equipped with electronic LED indication, the 4040 configuration uses a mechanical indicator and manual test facility.
Manual testing must be carried out under appropriate safety procedures because operating or locking the test button may energise connected machinery or electrical loads independently of the normal control signal.
The relay's rear flange mounting arrangement allows secure installation in machinery and electrical assemblies, while its Faston 250 quick-connect terminals support convenient wiring and servicing. These features make the Finder 62.82.9.012.4040 suitable for both new industrial equipment and compatible replacement applications.
