Description The multi-functional self-resetting protector incorporates over-voltage, under-voltage, over-current protections and a built-in smart protector. When there are solid barriers of overvoltage, undervoltage and overcurrent in the line, this product can instantly cut off the circuit, thus avoiding damage to electrical equipment. When the unnecessary circuit returns to normal, the protector can automatically restore the circuit to make the electrical equipment work normally. Features: Solid case design, with high shock resistance , wear resistance and can provide a long service life. Visual design window, the location is clear at a glance to prevent mishandling. High sensitivity, high reliability and stable working performance. Multi-functional dual-display auto-reset protector incorporates over-voltage, under-voltage, over-current protections and built-in 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 supply after the time set by the user, no manual operation is required.
