Voltage Protectors

Voltage Protectors — Over & Under Voltage Protection for Pakistan

Power fluctuations, neutral breaks, and load-shedding surges destroy appliances worth Rs.3,000 to Rs.300,000 every year in Pakistani homes and businesses. A CNC voltage protector sits on your DIN rail inside the DB box and disconnects the load the moment voltage crosses safe limits — typically above 275V or below 170V — then reconnects automatically once voltage stabilises. No manual reset, no electrician call-out, no damage.

All CNC voltage protection devices include auto-restart (self-recovery after power returns), adjustable voltage thresholds, and power-on delay (3-minute compressor protection for fridges and ACs). Every unit ships with a 5-year CNC warranty, IEC 61643 compliance context, and free delivery across Pakistan.

Which Voltage Protector Do You Need?

Single Phase (Home, Shop, AC, Fridge): The YC7VA series comes in 40A, 63A, and 80A options starting from Rs.2,200. Protects against over-voltage, under-voltage, and neutral break (440V spike protection). Best seller for residential and small commercial use.

Three Phase (Factory, Commercial, Industrial): The YC9VA 2-Pole handles single-phase loads on three-phase supply from Rs.3,200. The 4-Pole 63A version at Rs.6,000 covers full three-phase motor and machinery protection.

Auto Phase Switch: The YC6VAs series (63A and 100A) automatically switches between two power sources when voltage drops below safe limits. Ideal for generator-to-mains switching with voltage monitoring built in.

Common Questions — Voltage Protector Pakistan

Does it protect against neutral break (440V)? Yes. The YC7VA series is rated for 440V protection, which covers the dangerous neutral-break scenario that sends 380-440V into single-phase appliances.

What about the power-on delay for fridges and ACs? Critical feature. After a power cut, the voltage protector waits approximately 3 minutes before reconnecting. This protects compressor motors from back-to-back start damage.

Will it work for unattended water pumps? Yes. Auto-restart reconnects power automatically once voltage returns to safe range. No manual reset needed.

Voltage protector vs stabilizer? A stabilizer adjusts voltage continuously using a transformer — heavier, more expensive, and can fail under extreme fluctuations. A voltage protector simply disconnects when voltage is dangerous and reconnects when safe. For most Pakistani homes, a protector is the better value.

Voltage protector price in Pakistan: CNC voltage protectors range from Rs.2,200 (single-phase 40A) to Rs.6,000 (three-phase 63A). Free delivery across Pakistan with 5-year warranty.
