Voltage Limiter ON-375 for Protecting Power Supply Unit BPL 275-12

Voltage limiter ON-375 is designed to protect the power supply unit BPL 275-12 in the mine normal version PH from the increase in line voltage, protection from the damaging effects of impulse surges caused by switching close and connected to the same network loads of high power, thereby preventing equipment failure and possible fire with subsequent fire. The main application is in auxiliary equipment circuits of mine contact electric locomotives of nominal voltage 275 V DC.
