100A TOMZN 3 Phase 3P+N Din Rail Phase Selector Adjustable Over and Under Voltage Current protection Monitor Relays Protector
100A 3P+N rail phase selector with monitoring relay protector is reliable guarantee for power system. TOMZN. It is capable of correct selection of phase sequence and real-time monitoring of three-phase circuits. Overvoltage, undervoltage and current protection function adjustable, can flexibly set the protection threshold according to actual needs. Once the voltage or current is abnormal, through the fast action to cut off the circuit, to achieve the effective avoidance of equipment damage to the industrial and commercial electricity is stable protection.
