Reliable High-Current Switching for Industrial Equipment
The Finder 66.82.8.012.4300 operates through an electromagnetic coil that closes two normally open contact sets when energised. Applying the rated 12 V AC control voltage activates the relay, allowing two electrical circuits to be switched simultaneously. When the coil is de-energised, the contacts return to their normally open state, providing dependable control of connected electrical loads.
The Finder Series 66 is designed for demanding electrical switching duties in industrial and commercial equipment. The 66.82.8.012.4300 combines high-current silver tin oxide contacts, reinforced insulation and a practical flange-mounted construction with Faston connections. This arrangement makes it suitable for control panels, machinery and electrical equipment where secure mounting and accessible terminal connections are important.
