Field failure relay also known as FIELD LOSS RELAY protects the DC Shunt wound motor or main circuit, under open field conditions or in the absence of the field supply. Field failure relay manufacturers, traders, dealers, exporters and suppliers in Mumbai, Maharashtra, India to all over the world from 1970 according to ISO standards and client's requirements. Field failure relay DC motor supplied with industrial features and characteristics. Field loss relay price in India and overseas offered by us is low without compromising with quality of relays.
Speed of the Shunt Wound DC Motor increases as the Field supply is weakened. Theoretically motor runs at infinite speed if run without Field supply. This break opens the armature coils from the commutator and totally damages the Prime Mover.
Field failure relay when used in series with the Field circuit, ensures that no power is supplied to the Armature unless Field circuit is complete. Field failure relay is a truly current operated device. As there is no iron core, there is no magnetic storage and actuating time is less than 1.2 milliseconds
This is also used as safety guard in DC motor clutches, solenoids and brakes
* No external power supply needed instantaneous trips
* Can be increased with multiple turn
