Why Choose the Finder 66.82.8.230.4001 Power Relay?
The Finder 66.82.8.230.4001 is an industrial electromagnetic power relay from the Finder Series 66 range, designed for reliable switching of electrical loads in machinery, automation systems and power control equipment. Featuring a 230 V AC operating coil and a two-pole changeover contact arrangement (2 CO / DPDT), it provides flexible switching between normally open and normally closed electrical circuits.
The Finder 66.82 relay family is engineered for demanding power switching applications, combining high-current contacts with robust electromechanical construction. The relay's 30 A nominal normally open contact rating, 10 A normally closed contact rating and reinforced insulation between coil and contacts make the series suitable for industrial equipment requiring dependable electrical switching and control circuit isolation.
The 66.82.8.230.4001 belongs to the flange-mounted Series 66 relay range, which uses Faston 250 quick-connect terminals for practical equipment installation. Its 230 V AC coil supports conventional industrial AC control circuits, while the two changeover contact sets provide versatile switching functionality for heating equipment, machinery, power distribution auxiliaries and OEM electrical assemblies. The final 4001 configuration suffix should be checked against the manufacturer's ordering information when matching a specific replacement.

Reliable High-Current Switching for Industrial Electrical Equipment
The Finder 66.82.8.230.4001 uses an electromagnetic operating mechanism to control electrical loads through a separate coil circuit. When the 230 V AC coil is energised, the relay transfers its two changeover contacts from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their original state.
The Finder Series 66 is designed for power switching applications where substantial contact current capability and reliable electromechanical operation are required. Its double-pole changeover arrangement supports electrical load switching, circuit selection and interlocking functions. Reinforced insulation between the coil and contacts helps maintain separation between the control circuit and switched electrical loads.
The 66.82 flange-mounted construction and Faston 250 connections make this relay family suitable for installation in industrial machinery and OEM equipment. Correct selection requires consideration of the electrical load category, switching frequency, terminal current capacity, insulation requirements and operating temperature. The precise configuration associated with the 4001 suffix should be confirmed before replacement or installation.
