66.82.9.110.4000 Finder Power relay 2pole 30A DC 110V

Why Choose the Finder 66.82.9.110.4000 Power Relay?

The Finder 66.82.9.110.4000 is a high-current electromechanical power relay designed for dependable electrical switching in industrial automation, machinery control and power management systems. Part of the established Finder Series 66, this relay combines a 110 V DC operating coil, double-pole changeover contacts and robust flange-mounted construction for industrial electrical installations.

Featuring a double-pole double-throw (DPDT / 2 CO) contact arrangement, the Finder 66.82.9.110.4000 allows two independent electrical circuits to be switched simultaneously using a single electromagnetic coil. Its silver tin oxide (AgSnO2) contacts offer dependable performance in demanding switching applications, including equipment where electrical loads can produce significant inrush currents.

With 30 A normally open contacts, 10 A normally closed contacts and a 250 V AC rated contact voltage, the Finder 66.82.9.110.4000 is suitable for a wide range of industrial electrical control applications. Reinforced coil-to-contact insulation, a secure flange-mounted housing and Faston 250 quick-connect terminals make it a practical choice for machinery, heating systems, HVAC equipment and electrical control assemblies.

Dependable 110 V DC Control of High-Current Electrical Loads

The Finder 66.82.9.110.4000 enables a 110 V DC control circuit to operate higher-current electrical loads through mechanically isolated switching contacts. When the relay coil is energised, its electromagnetic mechanism transfers both changeover contacts from their normally closed positions to their normally open positions. When coil power is removed, the contacts return to their original states, providing predictable non-latching operation.

The Finder Series 66.82 combines high-current switching capability with reinforced electrical insulation, flange mounting and Faston 250 electrical connections. Its silver tin oxide contacts are particularly relevant where loads may generate elevated inrush currents, although the permissible switching duty must always be checked against the manufacturer's ratings. For DC-controlled installations, the coil driver should be correctly rated and suitable suppression should be considered to manage switching transients.
