VA 2 Pole Double Relay Protection Device 120V-300V 63A | Reliable Power Safety

Voltage protector is one of the fastest practical fixes for homes and small shops in Pakistan when voltage swings keep damaging appliances and control gear. This 2 pole 63A unit is listed at Rs.3,200 on CNC Electric Pakistan and is built for single-phase lines where you want overvoltage, undervoltage and current-related protection with a front display and adjustable delay. It suits apartments, homes, shops, pump panels and backup boards where supply quality is unpredictable but the incoming line is still single phase.

The key point is simple. This is not just a display relay. It watches the line, shows live voltage on the digital screen, and disconnects the load when the supply goes outside the set range. If your freezer, inverter, water pump, AC controller or shop electronics are suffering because WAPDA or K-Electric voltage keeps drifting too low or too high, this type of voltage protector is the practical first layer of protection before you move to bigger and costlier solutions.

Key Features

• Single-phase 2 pole voltage protector listed at 120V-300V and 63A on the live local page.
• Digital front display shows the current network voltage instead of leaving the user blind.
• User-adjustable voltage value and delay time, so the device can be tuned to the site instead of running one fixed threshold only.
• Stored settings remain in non-volatile memory after power loss, so you do not have to re-enter them after every outage.
• Load switching is done through an internal electromagnetic relay, which is why it behaves like a line monitor plus disconnect device.
• Local page positions it for residential buildings, non-residential buildings and small energy/infrastructure applications.
• Useful where you need a real voltage protector, not just a plug-top appliance saver.
• A good partner for surge protection devices, circuit breakers and a proper Voltage Protector Finder Tool.

Applications in Pakistan

This voltage protector makes most sense on incoming single-phase lines where supply quality is bad enough to damage loads but not bad enough to justify a full servo stabilizer on day one. In Karachi apartments and houses, it suits incoming protection for refrigerators, LED lighting circuits, washing machines, inverter lines and smaller AC circuits where K-Electric voltage can drift and then recover sharply. In Lahore shops, it suits cash counters, displays, freezers, UPS-backed sockets and office electronics where one bad evening of supply fluctuation can cause repeated shutdowns.

In Faisalabad or similar utility areas, this 2 pole voltage protector also works well on single-phase pump lines, water motors, farmhouse incoming boards and small workshop panels where the load still sits within 63A and the user wants automatic cut-off plus reconnection logic. It is also useful in homes that alternate between grid and small generator or inverter-backed supply, because the front display helps the user see what is actually arriving on the line instead of guessing.

How to Choose the Right Voltage Protector

Choosing the right voltage protector is mostly about network type, current and the kind of problem you are trying to solve. This 2 pole 63A model is for single-phase users who want disconnect-and-reconnect protection. If your site is three-phase, move to a 4 pole model. If your issue is not cut-off protection but the need to keep output voltage artificially stabilized for sensitive lab or testing work, a voltage regulator may be the better choice.

Voltage Protector vs Alternatives — Why CNC?

What This Product Does NOT Protect Against

This product does not replace a proper breaker, AC breaker, RCCB/RCBO, or a real surge protection device. It is also not a three-phase protection device. Its job is to monitor a single-phase line and disconnect the load when the supply goes outside the set range.

It also does not behave like a servo stabilizer. If the requirement is to keep output voltage continuously corrected instead of disconnecting and reconnecting, the right answer is a voltage regulator. And if lightning or switching surges are part of the problem, you still need an SPD near the panel.

Installation Guide

1. Mount the device in a proper enclosure or DB with the incoming single-phase line clearly identified.
2. Connect the line and load according to the product schematic supplied with the device or local installer instructions.
3. Set the upper and lower voltage values according to the real load and utility condition, not by guesswork.
4. Set the delay so compressors, pumps or restart-sensitive loads are not slammed back on immediately after supply returns.
5. Test the front display and output behavior before handing the panel over to the end user.

Frequently Asked Questions

What is a voltage protector?

A voltage protector is a device that monitors the supply line and disconnects the load when voltage rises too high or falls too low. This 2 pole unit is designed for single-phase lines and also shows live voltage on its front display.

What is the voltage protector price in Pakistan for this model?

At the time checked, the live CNC Electric Pakistan page lists this 2 pole 63A voltage protector at Rs.3,200.

Is 63A enough for a whole single-phase home?

For many homes and small shops, yes. The right answer depends on the actual incoming breaker size and running load. If the site current is higher or the main is three-phase, move to the correct larger model instead of forcing a 2 pole unit into the job.

Can this voltage protector be used with a generator or inverter?

Yes, it can be used on single-phase lines that alternate between grid and backup supply, provided the panel is designed correctly and the switching arrangement is proper. It helps the user see and control the actual line condition.

Is this the same as a voltage regulator or stabilizer?

No. A voltage protector disconnects when voltage goes outside the set range. A voltage regulator or stabilizer actively adjusts output voltage. They solve different problems.

Can this replace an MCB or RCCB?

No. You still need the right breaker and leakage protection where required. A voltage protector is one layer of protection, not the whole DB.

When should I choose a 4 pole voltage protector instead?

Choose a 4 pole voltage protector when the site is three-phase or the incoming board is built around a three-phase main. This 2 pole device is for single-phase lines.

Does it remember the settings after a power cut?

Yes. The local product description says the set values are stored in non-volatile memory, so the device does not forget its settings after normal power loss.

If your single-phase line keeps damaging loads or causing nuisance shutdowns, this 2 pole 63A voltage protector is the practical next step. It is listed at Rs.3,200 on CNC Electric Pakistan and gives a cleaner, more adjustable answer than cheap plug-in guards.
