Reliable 110 V DC Control for Industrial Power Switching
The Finder 66.82.9.110.4300 allows a 110 V DC control circuit to operate electrical loads through an electromechanical switching system. Energising the coil creates a magnetic field that operates the relay contacts, while removing the coil supply allows the mechanism to return to its normal state. This makes the relay useful for control systems where switching commands must be separated electrically from the load circuit.
The Finder Series 66.82 is designed for high-current industrial applications and incorporates reinforced coil-to-contact insulation, flange mounting and Faston electrical connections. These features support dependable installation and servicing in machinery and control equipment. When specifying this model, engineers should verify the exact contact arrangement and terminal identification against the manufacturer's product marking, and ensure that the selected contact ratings are appropriate for the actual resistive, inductive or motor load.
Typical Applications
- Industrial automation systems using 110 V DC control circuits.
- Electrical control panels and relay-operated machinery.
- Industrial heating systems, boilers and furnaces.
- Heating, ventilation and air conditioning (HVAC) equipment.
- High-current resistive load switching.
- Manufacturing and industrial processing equipment.
- Power generation and auxiliary control systems.
- Electrical distribution and power management assemblies.
- Industrial washing machines and commercial appliances.
- Motor auxiliary circuits within applicable contact ratings.
- OEM machinery requiring flange-mounted power relays.
- Electrical equipment requiring isolated control of power circuits.
