Tsubaki TSB50 Shock Relay

Description:

The Tsubaki TSB50 shock relay is an electronic overload protection device used in industrial motor control systems to detect excessive motor load and prevent mechanical damage. Commonly installed in conveyor systems, packaging machinery, material handling equipment, pumps, and other motor-driven industrial machines requiring overload monitoring. Maintenance teams and system integrators use this shock relay for equipment replacement, retrofit projects, and preventive maintenance to improve machine protection and reduce unplanned downtime.

Applications:

The Tsubaki TSB50 shock relay monitors motor current to detect overload conditions before equipment damage occurs. It is widely used in conveyor systems, bucket elevators, pumps, agitators, packaging equipment, food processing machinery, water treatment plants, and manufacturing systems where reliable motor protection helps extend equipment life and maintain continuous production.
