Yagi-Kripal UKH-220 Thermal Overload Relay 100-160A

Description:

The YAGI-Kripal UKH-220 100–160A thermal overload relay is used in industrial motor protection systems. Commonly installed in motor starters, control panels, and contactor assemblies to protect electric motors from overload and phase imbalance. Maintenance teams, electricians, and system integrators use this unit for motor protection, circuit safety, and prevention of equipment damage due to overheating.

Applications:

The YAGI-Kripal UKH-220 100–160A is used in industrial automation systems to monitor motor current and trip the circuit when overload conditions occur. It is widely applied in pumps, conveyors, compressors, and manufacturing equipment where reliable motor protection and operational safety are critical. These relays are typically mounted with contactors in motor control centers and help extend motor lifespan by preventing overheating and electrical faults.
