The TSB151 and TSB152 series SHOCK RELAY allows easy connection into new or existing applications. For single or3phase motors, simply wire the current transformer that we supply into1line of the motor and the SHOCK RELAY into the control circuit (stop-start circuit).
The SHOCK RELAY is powered by the same voltage as the control circuit to the motor starter, usually 115V or 230V single phase. If a different control voltage is used, a step down transformer may be required.
The supplied current transformer is then connected in1line of the motor that is being monitored. Motor voltages above 600 volts require special considerations.

- 1 If the starter coil in the magnetic contactor (MC) of the monitored motor exceeds the Shock Relay output contact’s capacity, an auxiliary relay must be installed to prevent damage to the Shock Relay. The instruction manual included with each Shock Relay details how to add this auxiliary relay if required.
