Why Choose the Finder 66.82.9.012.4000 Power Relay?
The Finder 66.82.9.012.4000 is a high-performance 30 A electromechanical power relay from the Finder 66 Series, designed for reliable electrical load switching in industrial automation, machinery, heating equipment and power control applications. Featuring a 12 V DC operating coil, flange-mounted construction and Faston 250 quick-connect terminals, it offers a practical solution for electrical control panels and OEM equipment.
This relay features a two-pole changeover (2 CO / DPDT) contact arrangement, allowing two independent electrical circuits to be switched between normally closed and normally open positions using a single control signal. Its changeover configuration supports flexible load control, auxiliary switching and electrical circuit selection.
With a 30 A normally open contact rating, 10 A normally closed contact rating and silver tin oxide (AgSnO₂) contacts, the Finder 66.82.9.012.4000 is suited to demanding industrial switching applications. Reinforced insulation between the coil and contacts provides additional electrical separation between low-voltage control circuits and switched loads.

Reliable Electrical Switching for Industrial Automation
Electromechanical power relays allow low-voltage control signals to operate higher-current electrical loads. When the 12 V DC coil of the Finder 66.82.9.012.4000 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, enabling controlled switching between electrical circuits.
The Finder 66.82.9.012.4000 provides a practical switching solution for industrial machinery, heating equipment, control panels and automated electrical assemblies. Its dual changeover contacts provide flexibility for load selection and auxiliary switching, while flange mounting and Faston quick-connect terminals simplify installation. Engineers should assess the actual electrical load, starting current and switching frequency against the applicable relay ratings before installation.
Typical Applications
- Industrial automation and electrical control panels.
- Industrial heating equipment, boilers and burners.
- HVAC and air conditioning control systems.
- Industrial washing machines and commercial appliances.
- Backup generator and power management equipment.
- Industrial machinery and OEM electrical assemblies.
- Electrical load switching and circuit selection.
