Why Choose the Finder 62.83.9.125.4000 Power Relay?
The Finder 62.83.9.125.4000 is a robust 16 A industrial electromechanical power relay designed for dependable electrical switching in industrial automation, machinery and control systems. Part of the established Finder 62 Series, this relay combines a 125 V DC operating coil with three changeover contacts, making it suitable for industrial equipment using higher-voltage DC control circuits.
Featuring a three-pole double-throw (3PDT / 3 Form C) contact configuration, the Finder 62.83.9.125.4000 provides three independent changeover contacts operated simultaneously by a single coil. Its silver tin oxide (AgSnO₂) contact material supports dependable switching performance, while the non-latching electromechanical design ensures that the contacts return to their normal positions when the coil is de-energised.
With a 16 A rated contact current, 250 V AC rated contact voltage and 125 V DC coil supply, this relay is suitable for industrial control panels, electrical equipment and automation applications.

Reliable Three-Pole Switching for 125 V DC Control Systems
The Finder 62.83.9.125.4000 operates as an electrically controlled switch. When its 125 V DC coil is energised, the relay transfers all three changeover contacts from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their normal states. This allows a single DC control signal to operate three independent electrical circuits simultaneously.
The 3PDT contact arrangement provides greater switching flexibility than a relay with normally open contacts only. Each pole has a common, normally closed and normally open connection, making the relay suitable for auxiliary switching, changeover functions, signalling and electrical control applications. Its silver tin oxide contacts are designed for repeated operation within the manufacturer's specified electrical ratings.
The 125 V DC coil makes this relay particularly useful in control systems designed around a nominal 125 V DC supply. The Faston 250 terminals simplify connection with compatible receptacles, while the rear flange mounting arrangement provides secure installation within electrical equipment. The standard 4000 configuration provides straightforward relay operation without an integrated manual test button or mechanical indicator.
Typical Applications
- Industrial automation and electrical control panels.
- Electrical control systems using 125 V DC supplies.
