Why Choose the Finder 62.33.8.120.4000 Industrial Power Relay?
The Finder 62.33.8.120.4000 is a 16 A industrial plug-in power relay from the Finder 62 Series, designed for dependable electrical switching in industrial automation, machinery and control panel applications. Featuring a 120 V AC operating coil and three changeover contacts (3PDT / 3 CO), this relay enables three independent electrical circuits to be controlled simultaneously using a single alternating-current control signal.
Unlike two-pole relays, the Finder 62.33.8.120.4000 provides three independent changeover contact sets, each offering normally open and normally closed switching functions. This makes it particularly useful for applications involving multiple auxiliary circuits, electrical interlocking, control logic and coordinated equipment operation. Its silver tin oxide (AgSnO2) contacts provide a cadmium-free contact material suited to demanding industrial switching duties.
With a 16 A rated contact current, 250 V AC rated contact voltage and 4000 VA AC-1 switching capacity, the relay is suitable for appropriately rated industrial electrical loads. Its plug-in construction, Faston 187 quick-connect terminals and compatibility with selected Finder 92 Series sockets support convenient installation and maintenance. The standard 4000 configuration provides straightforward electromagnetic switching without an integrated LED indicator or manual test button.

Reliable 120 V AC Control with Three Independent Changeover Contacts
The Finder 62.33.8.120.4000 operates through an electromagnetic coil that controls three independent changeover contacts. When the 120 V AC coil is energised, each common contact transfers from its normally closed position to its normally open position. When the coil supply is removed, all three contacts return to their normal positions. This 3PDT arrangement allows three circuits to be switched together, making it useful for auxiliary control, electrical interlocking, equipment sequencing and industrial automation applications.
The relay's three-pole contact arrangement offers greater switching flexibility than a two-pole relay without requiring multiple separate devices. Its Faston 187 terminals and plug-in construction allow straightforward replacement when used with an appropriately rated Finder 92 Series socket. The 120 V AC coil must be supplied from a compatible AC control circuit, and the switching capacity of each contact must be checked against the connected load. In particular, the 16 A AC contact rating must not be assumed to apply to high-voltage DC loads, which have substantially different breaking-capacity limits.
