Finder 66.82.8.120.1003 is a Series 66 flange-mounted electromechanical power relay featuring a 120 V AC coil, two changeover contacts, 30 A normally open contact rating and Faston 250 terminals for industrial electrical switching and automation applications.
Why Choose the Finder 66.82.8.120.1003 Power Relay?
The Finder 66.82.8.120.1003 is an industrial 30 A electromechanical power relay belonging to the Finder Series 66 range of high-current switching relays. Designed for electrical control, industrial automation and power switching equipment, the relay combines a robust electromagnetic switching mechanism with practical flange mounting and quick-connect terminals.
Featuring a 120 V AC operating coil and a two-pole changeover contact arrangement (DPDT), the Finder 66.82.8.120.1003 enables electrical loads to be controlled through an independent AC control circuit. Its flange-mounted construction and Faston 250 terminals make the Series 66.82 format suitable for installation in industrial machinery, electrical control panels and commercial equipment.
The Series 66 contact system provides a 30 A normally open contact rating and a 10 A normally closed contact rating, with a nominal switching voltage of 250 V AC. Reinforced insulation between the coil and contacts helps provide dependable separation between control and load circuits, supporting reliable operation in demanding electrical applications.

Reliable Power Switching for Industrial Control Systems
The Finder 66.82.8.120.1003 uses an electromagnetic coil to operate two changeover contact sets. When the rated 120 V AC control supply is applied, the relay transfers its contacts from their normal positions to their energised positions, allowing connected circuits to be controlled independently of the coil supply. When the coil is de-energised, the contacts return to their normal state.
The Finder Series 66 is developed for demanding industrial and commercial switching duties. Its high-current contact system, reinforced insulation and robust mechanical construction make it suitable for electrical machinery, heating equipment, automation panels and power control assemblies. The flange-mounted design with Faston terminals also supports straightforward wiring, maintenance and equipment integration.
Typical Applications
- Industrial automation and electrical control systems.
- Heating, ventilation and air conditioning equipment.
