How It Works: Voltage Relay. Currents flow through the relay coil, creating a magnetic field. The field attracts the switch lever and enables it to change position. Voltage switches typically offer two positions based on whether the coil's current is on or off. Voltage relays can be over-voltage relays, under-voltage relays or a combination.

OVER VOLTAGE RELAY. UNDER VOLTAGE - OVER VOLTAGE RELAY model made by ITI Palana WM Staff & Trainees.
Under Voltage Relay. Experiment performed in protection lab by Mahesh Ahuja.
Where Are The Wiring Diagrams For Undervoltage Trips (MN. The shunt trip will trip the circuit breaker if control voltage is applied across the two shunt trip terminals. The undervoltage trip will trip the circuit breaker if control voltage is removed from the two undervoltage trip terminals. Here are links to the instruction bulletins for the shunt trips and undervoltage trips of the Powerpact Breakers
