3Phase AC tomzn SPD 4pole House Surge Protector voltage Arrester Device in Pakistan

The Tomzn 3Phase AC SPD 4pole House Surge Protector Voltage Arrester Device in Pakistan is designed to protect your home or small commercial building from dangerous voltage surges. Additionally these surges are often caused by lightning, grid switching or faulty wiring. In a result, this can damage TVs, ACs, fridges, computers and other electrical equipment.

This Tomzn SPD (Surge Protection Device) is made for 3‑phase AC systems (230/400V) and uses a 4‑pole design to protect all three phases and neutral. Installed inside the main distribution board (DB), it safely diverts surge energy to earth, reducing the voltage that reaches your appliances.

Furthermore the compact, DIN‑rail mount housing allows easy installation alongside MCBs and RCCBs. 

Indicator windows—available on select models—clearly display the health status of the protection module. Moreover, it ensures you maintain optimal surge protection at all times. 

Moreover this SPD is suitable for houses, small factories, shops, offices and mixed‑use buildings using a 3‑phase supply.
