Why Choose the Finder 62.33.8.012.4000 Power Relay?
The Finder 62.33.8.012.4000 is a robust three-pole electromechanical power relay designed for dependable electrical switching in industrial automation, machinery control and electrical control panels. Part of the established Finder 62 Series, this model features a 12 V AC operating coil, three changeover contacts (3 CO / 3PDT) and silver tin oxide contact material, providing a versatile switching solution for industrial electrical equipment.
The relay's three independent changeover contacts allow three electrical circuits to be controlled simultaneously using a single coil signal. Each contact set includes common, normally open and normally closed connections, making the relay particularly useful for electrical interlocking, multi-circuit switching, auxiliary control and industrial signalling. The AgSnO2 contact material offers good resistance to contact welding and supports reliable operation with appropriately rated electrical loads.
The Finder 62.33.8.012.4000 combines a plug-in construction with Faston 187 quick-connect terminals, making it suitable for electrical control assemblies where convenient wiring and relay replacement are important. Its standard configuration provides straightforward electromagnetic switching without additional manual test or electronic indication functions. With a 12 V AC coil, three changeover contacts and industrial-grade construction, it is a practical choice for electrical engineers, automation specialists and maintenance professionals.

Reliable Three-Pole Switching for Industrial Control Systems
The Finder 62.33.8.012.4000 operates through an electromagnetic switching mechanism. When its 12 V AC coil is energised, the internal armature transfers all three changeover contacts from their normally closed positions to their normally open positions. This allows a single control signal to switch three separately wired electrical circuits. When the coil supply is removed, the contacts return to their normal positions, providing conventional monostable operation.
The 3PDT contact arrangement distinguishes this relay from two-pole models in the Finder 62 Series. The additional changeover contact is particularly useful where an application requires three coordinated switching functions, such as controlling auxiliary equipment while simultaneously providing status or interlocking signals. Its Faston 187 terminal arrangement supports convenient connection and replacement. The appropriate contact ratings, socket compatibility and insulation requirements should always be checked against the manufacturer's documentation for the exact relay and installation.

The Finder 62.33.8.012.4000 is a three-pole electromechanical power relay used for switching electrical circuits in industrial automation, machinery control and electrical panels. Its three changeover contacts allow three independent circuits to be controlled simultaneously using a single 12 V AC coil.
What coil voltage does the Finder 62.33.8.012.4000 require?
The relay requires a 12 V AC nominal coil supply operating at 50/60 Hz. The nominal coil consumption is approximately 2.2 VA. It is intended for compatible AC control circuits and should not be connected directly to a 12 V DC supply.
What does 3 CO or 3PDT mean?
3 CO means three changeover contacts, while 3PDT means triple-pole double-throw. Each pole provides a common, normally open and normally closed connection. All three contact sets operate together when the relay coil is energised, allowing three independent circuits to be switched with one control signal.
What is the contact rating of the Finder 62.33.8.012.4000?
The Finder 62.33 relay family has a 16 A nominal contact rating, with a 250 V AC rated contact voltage and 400 V AC maximum switching voltage. The exact permissible load depends on the contact configuration, load type and operating conditions, so the manufacturer's specifications should be checked before installation.
