Voltage swings are a daily fact in Pakistan: low voltage at peak hours, high voltage at night and surges when supply returns after load-shedding. Air conditioners, fridges, pumps and machines suffer most. A voltage protector cuts the supply when the voltage goes outside safe limits and reconnects automatically after a delay once it is stable again.
TOMZN's DIN-rail TOVPD1 protectors (single-phase, 40 A and 63 A) show the live voltage and current and let you set the over-voltage, under-voltage and over-current trip points and the reconnect delay. The TOVPD1-63DK disconnects both live and neutral. The three-phase TOVPD3-63VA adds phase-loss, phase-sequence and asymmetry protection for motors. For individual appliances, the plug-in TOVS-16Z and TOSVA-16 protect a single socket.
We supply TOMZN protectors for homes, shops, offices and machine panels. Tell us the load current and whether the supply is single or three-phase, and we recommend the right protector.
