Relay Product and Bush

Hind asia industries manufactures designs and manufactures field failure relay. This mostly known as field loss relay. It is used to protect dc shunt wound motor or main circuit. Field failure relay operates on current. There is no magnetic storage because there is no iron core. The actuating time is less than 1.2 milliseconds. Field failure relay can also be used as dc clutches, solenoids and brakes. This is highly reliable and provides excellent service. 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


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. The 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 clutches, solenoids and brakes
