The TSB151 and TSB152 series SHOCK RELAY allows easy connection into new or existing applications. For single or three phase motors, simply wire the current transformer that we supply into one line 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 in one line of the motor that is being monitored. Motor voltages above 600 volts require special considerations. /Asset/TSB151_ShockRelay--1.jpg
TSB151, TSB152 Shock Relay for Overload Protection
(2) U.S. Tsubaki SHOCK RELAY monitors the change in motor current that closely approximates the torque output of the motor. Should the motor current exceed the preset LOAD CURRENT point for a preset length of SHOCK TIME (continuous overload time), the SHOCK RELAY will shut down the motor power supply.The TSB151 and TSB152 series SHOCK RELAY allows easy connection into new or existing applications.

TSBSB Shock Relay for Overload Protection
(7)- TSBSB Shock Relay series – Overload protection has built-in reset button, test button, fail-safe contacts with manual and automatic reset feature
TSBSB Shock Relay senses the problem before downtime, maintenance and equipment damage occur, saving you time and money. Install it on a line, set the overload parameters, and Shock Relay takes care of the rest. If an overload is detected, the Shock Relay can send a warning or shut down the line – quick and reliably. Correct the problem and you’re up and running again in minutes.
