The primary function of these contactors is to keep a circuit connected until a power supply energises the coil, opening the circuit.

Ideal for fail safe application in emergency systems on a variety of equipment such as industrial machinery, continuous power or motor control where equipment must stay energised until a specific condition arises such as an emergency stop button being pressed in the circuit, in the event of an emergency or critical condition.

Comes with 2 x 9mm spacers for heat dissipation.
