3 Phase Protector, 63A Multifunctional Self Resetting Over Under Voltage Protector with Visual Window Design, for Overcurrent Overvoltage Undervoltag

housing design, with high resistance, wear resistance and can provide service time. Visual window design, the location is clear at a to aviods mis . High sensitivity, high reliablility and with stable working performance. The multifunctional self-resetting protector integrates over-voltage protections, under-voltage protections, over-current protections and integrated intelligent protector. When there is over-voltage, under-voltage and over-current barriers in the line, this product can instantly cut off the circuit, avoiding damage to electrical equipment. When the unnecessary circuit returns to normal, the protector can automatically the circuit to make the electrical equipment work normally. Features: housing design, with high resistance, wear resistance and can provide service time. Visual window design, the location is clear at a to aviods mis . High sensitivity, high reliablility and with stable working performance. Multifunctional self-resetting dual display protector integrates over-voltage protections, under-voltage protections, over-current protections and integrated intelligent protector.  When the line has overvoltage, undervoltage and overcurrent faults, the product will automatically cut off the line.  When the line voltage or current returns to normal, the product will automatically resume normal power supplys after the delay time set by the user, no manual is required.
