Why Choose the Finder 66.82.8.110.0003 Power Relay?

The Finder 66.82.8.110.0003 is a heavy-duty industrial electromechanical power relay featuring a 110 V AC coil and two changeover contacts (DPDT / 2 CO). Part of the established Finder 66 Series, it is designed for dependable switching in industrial machinery, electrical control panels, heating equipment and automation systems.

Unlike the two normally open configuration of the Finder 66.82.8.110.0303, the 66.82.8.110.0003 features two independent changeover contacts. Each contact transfers between normally closed and normally open connections when the coil is energised. This arrangement allows a single control signal to switch two separate circuits, making the relay useful for control changeovers, auxiliary switching and electrical interlocking applications.

With its 110 V AC nominal coil, silver-cadmium oxide (AgCdO) contacts, panel mounting and Faston 250 quick-connect terminals, the Finder 66.82.8.110.0003 offers a practical switching solution for industrial equipment. Its robust construction and monostable operation support dependable performance in applications requiring high-current relay contacts and convenient chassis installation.

Reliable Dual-Circuit Switching for Industrial Automation

The Finder 66.82.8.110.0003 enables industrial electrical circuits to be switched through a separate electromagnetic control circuit. When the 110 V AC coil is energised, the relay operates both changeover contacts simultaneously. Each contact transfers from its normally closed connection to its normally open connection, allowing two independent circuits to change state using a single control signal.

The Finder 66 Series is designed for industrial applications where reliable electrical switching, robust contacts and practical installation are essential. The 66.82.8.110.0003 combines AgCdO changeover contacts with a panel-mounted construction and Faston 250 connections, making it suitable for OEM machinery, industrial control assemblies and equipment maintenance. Connected loads must be selected according to the manufacturer's applicable current, voltage and switching-category ratings.

Typical Applications

  • Industrial automation and electrical control panels.
  • Industrial machinery and manufacturing equipment.
  • Electrical changeover and interlocking circuits.
  • Industrial heating and process control equipment.
  • Burner, boiler and oven control systems.
  • Motor control auxiliary circuits.
  • Industrial power distribution and load management equipment.
  • HVAC and ventilation control systems.
  • Industrial signalling and alarm circuits.
  • OEM machinery requiring dual changeover power contacts.
