Protector Trip Relays

General Details

Protector Trip Relays

Protector Trip Relays continuously monitor and protect any electrical parameter within a set point limit. The range offers both traditional and technologically advanced products, including single parameter units.

Features include Adjustable set point or set points, and adjustable time delay on selected models. Bright red LEDs are used for indicating alarm and trip function. There is continuous surveillance of all the major electrical parameters. This series offers a comprehensive range of possible input applications. Units are IP50 rated.

Advantages of Protector Trip Relays are that these units are one of the critical components of the electrical power grid that serve to detect defective equipment or other dangerous or intolerable conditions and can either initiate or permit switching or simply provide an alarm to provide a safer, more reliable delivery system.
