Tsubaki Chain Co., Ltd. TSBI52 Shock Relay Unit

Description:

The Tsubaki Tsubakimoto TSBI52 Shock Relay is used in industrial motor protection systems to detect overload conditions and protect mechanical equipment from damage. Commonly installed on conveyors, feeders, lifting equipment, and industrial machinery requiring electrical overload monitoring. Maintenance teams and system integrators use this shock relay for repair, replacement, retrofit, and improving equipment protection reliability.

Applications:

The Tsubaki TSBI52 Shock Relay is designed to monitor motor current and quickly detect abnormal increases caused by jams, overloads, or mechanical failures. It provides a protective signal when motor current exceeds the preset threshold for a specified duration, helping prevent damage to motors, chains, conveyors, and driven equipment. Tsubaki Shock Relays are commonly used in conveyor systems, lifting equipment, and industrial automation applications.
