Reliable High-Current Switching for Industrial Equipment
The Finder 66.82.8.230.4300 operates through an electromagnetic coil that closes two normally open contact sets when energised. Applying the rated 230 V AC control voltage activates the relay, allowing two independent electrical circuits to be switched simultaneously. When the coil is de-energised, both contacts return to their normally open positions, interrupting the connected loads.
The Finder Series 66 is designed for demanding industrial and commercial switching applications. The 66.82.8.230.4300 combines high-current silver tin oxide contacts, reinforced insulation and robust electromagnetic construction to support reliable operation in machinery, heating equipment and power control systems. Its flange-mounted design with Faston terminals also provides practical installation and maintenance advantages.
