66.22.8.024.1001 Finder Power relay 2pole 30A 24V

Why Choose the Finder 66.22.8.024.1001 Power Relay?

The Finder 66.22.8.024.1001 is a heavy-duty 30 A electromagnetic power relay designed for reliable electrical switching in industrial automation, machinery control and commercial equipment. Featuring a 24 V AC operating coil and a 2 changeover (DPDT) contact configuration, this relay enables a low-voltage AC control circuit to operate two separate electrical switching circuits.

Part of the established Finder 66 Series power relay range, the 66.22.8.024.1001 combines high-current switching capability with silver nickel (AgNi) contacts, direct printed circuit board (PCB) mounting and a wash-tight RT III enclosure. Its bifurcated PCB terminals provide a robust soldered connection, while the changeover contacts offer flexible switching between normally closed and normally open circuits.

With a 30 A normally open contact rating, 10 A normally closed contact rating and 250 V AC rated contact voltage, the Finder 66.22.8.024.1001 is suitable for industrial heating equipment, automated machinery, commercial appliances and OEM electronic control assemblies. Its reinforced insulation between the coil and contacts makes it particularly useful in equipment designs requiring dependable electrical separation between control and load circuits.

Reliable Dual-Pole Switching with Reinforced Electrical Insulation

The Finder 66.22.8.024.1001 enables a 24 V AC control circuit to operate two independent changeover contact sets. When the electromagnetic coil is energised, each common contact transfers from its normally closed terminal to its normally open terminal. Removing the coil supply returns both contacts to their de-energised positions, allowing two electrical circuits to be controlled by a single relay.

The relay's 30 A normally open contact rating, 10 A normally closed contact rating and AgNi contact material provide flexibility for industrial switching applications. Its DPDT configuration is useful where a control system needs to select between alternative circuits, change equipment operating states or provide coordinated switching functions. The different NO and NC current ratings must be considered when designing the connected circuits.

A key advantage of the Finder 66 Series is its reinforced insulation between the coil and contacts, supported by 8 mm creepage and clearance distances and a 6 kV impulse withstand rating. The RT III wash-tight construction also supports appropriate manufacturing processes for PCB-mounted equipment. Suitable coil protection, contact suppression, PCB copper dimensions and electrical clearances should be incorporated into the final design.
