Finder 62.33.9.036.4040 – 62 Series Power relays

Why Choose the Finder 62.33.9.036.4040 Power Relay?

The Finder 62.33.9.036.4040 is a 16 A electromagnetic power relay with a 36 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 three-pole relay combines high-current switching capability, versatile changeover contacts and a convenient plug-in design.

Featuring three changeover contacts (3 CO / 3PDT), the Finder 62.33.9.036.4040 enables three independent electrical circuits to be controlled simultaneously using a single DC control signal. Its silver tin oxide (AgSnO2) contact material provides resistance to contact welding, making it suitable for appropriately rated industrial switching applications.

A distinguishing feature of the 4040 configuration is its lockable test button with mechanical indicator. This provides a practical means of checking relay operation and identifying the contact position during commissioning, testing and maintenance. Combined with a 36 V DC coil, 16 A rated contacts and plug-in mounting, the relay offers a versatile solution for industrial control systems.

Technical note: The contact ratings are based on Finder's 62.33 relay specifications, while the 4040 suffix identifies the silver tin oxide contact material, lockable test button and mechanical indicator configuration. Confirm the exact coil characteristics, applicable approvals and installation requirements against the manufacturer's current product documentation before final engineering selection.

Reliable 36 V DC-Controlled Switching with Manual Test Function

The Finder 62.33.9.036.4040 enables three electrical circuits to be controlled through a single 36 V DC operating coil. When the coil is energised, the relay's electromagnetic mechanism transfers all three 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 3PDT contact arrangement provides flexibility for industrial control applications because each contact set can switch between two electrical paths. This makes the relay suitable for control logic, equipment interlocking, signalling and coordinated switching applications where multiple functions must respond to the same control signal.

The lockable test button provides an additional commissioning and maintenance feature. With the button in its standard momentary operating mode, pressing it manually operates the relay contacts, which return when the button is released. The test button can also be configured for locking operation according to Finder's instructions. This function must be used only under appropriate safe testing conditions because manually operating the relay can energise connected equipment.

The mechanical indicator provides visual confirmation of the relay's operating state, helping maintenance personnel identify contact actuation during inspection and troubleshooting. Unlike variants equipped with electronic LED indication, the 4040 configuration uses a mechanical indicator and manual test facility.

Installation using a compatible Finder 92 Series socket allows convenient relay replacement without extensive rewiring, supporting efficient maintenance in industrial control panels and machinery installations.
