66.82.9.024.4300 Finder Power relay 2pole 30A DC 24V

Why Choose the Finder 66.82.9.024.4300 Power Relay?

The Finder 66.82.9.024.4300 is a robust 30 A electromechanical power relay from the Finder 66 Series, designed for dependable electrical load switching in industrial automation, heating equipment, machinery and power control systems. Featuring a 24 V DC operating coil, two normally open contacts and a flange-mounted construction, this relay provides a practical solution for industrial control panels and OEM electrical equipment.

The relay incorporates a two-pole normally open (2 NO / DPST-NO) contact configuration, enabling two independent electrical circuits to be switched simultaneously through a single control signal. Its silver tin oxide (AgSnO₂) contacts provide switching capability for demanding electrical loads, while the non-latching electromagnetic mechanism ensures that both contacts return to their open positions when the coil is de-energised.

With a 30 A rated contact current, 250 V AC rated contact voltage and 7500 VA rated resistive switching capacity, the Finder 66.82.9.024.4300 is suitable for appropriately rated industrial electrical applications. Its Faston 250 quick-connect terminals, flange mounting and reinforced coil-to-contact insulation support convenient installation and reliable integration into electrical assemblies.

Reliable High-Current Switching for Industrial Automation

Electromechanical power relays enable low-voltage control systems to operate higher-current electrical loads through mechanically actuated contacts. When the 24 V DC coil of the Finder 66.82.9.024.4300 is energised, its electromagnetic mechanism closes both normally open contacts, allowing current to flow through the connected circuits. When coil power is removed, the contacts return to their normally open positions.

The Finder 66.82.9.024.4300 is particularly useful in industrial control systems where a 24 V DC control signal must operate two electrical loads or circuits simultaneously. Its AgSnO₂ contacts support power-switching applications, while reinforced insulation, flange mounting and Faston terminals facilitate integration into machinery, electrical panels and OEM equipment. Engineers should assess the load category, operating voltage, inrush current and switching frequency against the manufacturer's specifications before installation.
