VA Protection Device 4 Pole 3 Phase 63A, 100A | Durable Power Control

Voltage protector is the right product when a three-phase panel is being hit by unstable supply, harsh recovery after outages, over-voltage, under-voltage or abnormal current conditions. This 4 pole three-phase unit is listed in Pakistan at Rs.6,000 for 63A and Rs.7,000 for 100A on the live product page. For CNC Electric Pakistan buyers, it is a practical way to protect motors, compressors, pumps and service boards from bad supply behavior before the damage bill becomes bigger than the protection cost.

Key Features

• Three-phase voltage protector with local sale variants at 63A and 100A.
• 4 pole format for three-phase panels where full line control is needed.
• Digital display for voltage and current monitoring.
• Local page names overload protection, short-circuit protection and control function.
• Microprocessor-based relay logic with adjustable values and delay control from the official YC9VA-3 family description.
• Settings are stored in non-volatile memory according to the official family description.

Applications — Where to Use This 3 Phase Voltage Protector

A three-phase voltage protector like this is best where supply quality is the real threat. In Faisalabad process and textile settings, delayed reconnection can save motors and controls after unstable restoration. In Lahore workshops and mixed commercial buildings, it helps protect pumps, compressors and service boards when supply returns after load shedding. In Karachi, it suits K-Electric users running three-phase equipment who want the panel to disconnect when voltage conditions move outside the allowed set values.

How to Choose the Right Voltage Protector

Do not size only by price. Size by actual feeder current and by the value of the downstream equipment. If the board carries heavier current or the connected equipment is expensive to restart, stepping up to the correct amperage is usually cheaper than repairing a motor or controller later.

Voltage Protector vs Alternatives — Why CNC?

What This Product Does NOT Protect Against

This product does not replace every protection device in the panel. It does not replace the right circuit breaker or MCCB breaker for short-circuit coordination. It does not stop lightning or switching surge energy on its own, which is why a proper surge protection device is still important. It is also not a source-transfer device, so if the job needs mains-generator or mains-inverter switching, you still need the right automatic transfer switch or changeover breaker.

Installation Guide

1. Confirm the actual three-phase feeder current before choosing 63A or 100A.
2. Mount the device in a clean panel with correct conductor sizing and firm terminations.
3. Set the protection thresholds and recovery delay according to the site requirement and equipment being protected.
4. Keep the correct upstream breaker, surge protection and panel coordination around it.
5. Test the disconnect and recovery behavior before handing over the job.

Frequently Asked Questions

What is a 3 phase voltage protector used for?

It disconnects three-phase loads when voltage or current conditions move outside the set values, then reconnects after the delay.

What price is this voltage protector in Pakistan?

The live local page currently shows Rs.6,000 for the 63A option and Rs.7,000 for the 100A option.

What is the difference between 63A and 100A in this product?

The difference is current capacity. The 63A option suits more moderate three-phase panels, while the 100A option is for heavier feeder current.

Can this replace an SPD?

No. A voltage protector and an SPD do different jobs.

Can this replace an ATS or changeover switch?

No. It is not a transfer device. If the site needs mains-generator or mains-inverter switching, you still need ATS or changeover hardware.

Is this good for generators and load shedding conditions in Pakistan?

Yes. Where supply returns roughly after outage events, a voltage protector helps stop reconnection under bad conditions.

Can I use this on a commercial three-phase panel?

Yes, provided the actual feeder current matches the selected variant and the board still has the correct breakers and surge protection around it.

Does this product show voltage and current on screen?

Yes. Both the local page and the official family description describe it as a voltage and current display relay.

This 3 phase voltage protector is the right buy when the real problem is unstable supply quality, not just switching or isolation. It gives you a practical way to protect three-phase motors, service boards and commercial equipment from bad reconnection conditions.
