Used in the switching of motors, capacitors, lights etc. (Orlando) $99 Move in Special! One of the ways to reduce the heat generated is by carefully choosing the materials of the switch contact such that they have lesser resistance. the relay detects severe CT saturation, the overcurrent elements can operate on the adaptive current algorithm. Applying a lower voltage to a coil can cause what to happen? On the secondary side, we have our load circuit, the circuit on which we have to perform the switching, connected between the normally open and common terminal of the relay. The generated back-EMF opposes line voltage and can be measured across the start winding or across the coil of the potential relay at terminals 2 and 5.
