Description :
The relay operates on the differential system of protection provided by the double slide mechanism. Under single phasing and unbalanced voltage conditions, the two slides of the relay undergo differential deflection. One slide senses the movement of the bimetal that has deflected the maximum, while the other senses the minimum deflection. The slides are linked in such a way that the difference in movements of the two slides is amplified for actuation of the trip lever. This leads to accelerated tripping under single phasing.
features :
The heating elements in the main circuit heat the bimetal tripping elements corresponding to the motor load current. The heating elements are calibrated such that the set trip point is achieved in accordance with the standards. By means of trip bar, the movement / deflection of the bimetal is transmitted to plunger which in turns operates the trip mechanism and thus the contacts are separated.
The trip point can be easily set on a scale in accordance with the nominal motor rated current.
Bimetal elements for compensating the trip point in case of different ambient temperature is fitted on the trip lever. Buttons are used for testing the circuit to be protected, for resetting by hand and for conversion from manual to auto reset mode.
