Why Choose the Finder 66.82.9.012.4300 Power Relay?
The Finder 66.82.9.012.4300 is a high-current 30 A electromechanical power relay from the Finder 66 Series, designed for reliable electrical switching in industrial automation, machinery, heating equipment and power control systems. Featuring a 12 V DC operating coil, flange mounting and Faston 250 quick-connect terminals, this relay provides a practical solution for industrial electrical panels and OEM equipment.
The relay features a two-pole normally open (2 NO / DPST-NO) contact arrangement, allowing two independent electrical circuits to be switched simultaneously using a single control signal. Its silver tin oxide (AgSnO₂) contacts are designed for demanding power-switching applications, while the electromagnetic operating mechanism provides straightforward, non-latching switching functionality.
With a 30 A rated contact current at 250 V AC, a 7500 VA resistive switching capacity and reinforced insulation between the coil and contacts, the Finder 66.82.9.012.4300 is suitable for appropriately rated industrial electrical loads. Its flange-mounted construction and 6.3 × 0.8 mm Faston terminals support secure installation and convenient electrical connections.

Reliable High-Current Switching for Industrial Automation
Electromechanical power relays allow low-voltage control circuits to operate higher-current electrical loads through mechanically actuated contacts. When the 12 V DC coil of the Finder 66.82.9.012.4300 is energised, its electromagnetic mechanism closes both normally open contacts, allowing current to flow through the connected load circuits. When coil power is removed, the contacts return to their normally open positions.
The Finder 66.82.9.012.4300 provides a practical switching solution for industrial machinery, heating systems, power management equipment and automated electrical assemblies. Its dual normally open contacts enable simultaneous switching of two circuits, while AgSnO₂ contact material, flange mounting and Faston connections support reliable integration into suitable industrial equipment. Engineers should verify load characteristics, inrush current, switching frequency and operating conditions against the manufacturer's specifications before installation.
