Smart 63A Automatic Adjustable Voltage & Current Protector Relay with Dual Digital LED Display

The 63A Automatic Adjustable Voltage & Current Protector is an essential smart digital power protection relay engineered to shield solar inverters, residential appliances, and commercial equipment across Pakistan from harmful electrical grid anomalies. Featuring instantaneous micro-controller monitoring and a dual LED display showing live voltage (V) and current (A), this unit automatically disconnects power within 0.1 seconds when voltage drops too low (brownout) or surges too high, and automatically reconnects once grid electricity stabilizes.

Key Technical Features & Settable Parameters:

• Rated Current: 63A continuous load capacity (handles up to 13.8kW single phase load; suitable for 3kW to 10kW solar inverters).
• Over-Voltage Protection Range: Settable from 230V to 300V (Default: 270V).
• Under-Voltage Protection Range: Settable from 140V to 210V (Default: 170V).
• Over-Current Protection Range: Settable from 1A to 63A (Default: 40A / 63A).
• Action Trip Delay Time: Ultra-fast response from 0.1s to 10s (Default: 0.1s).
• Power Recovery Delay Time: Settable from 1s to 500s (Default: 30s; ensures compressor motors and inverters stabilize before re-energizing).
• Digital Dual LED Display: Real-time simultaneous readout of grid voltage and live amperes load.
• Calibration Capability: Manual voltage and current calibration fine-tuning for high accuracy.
• Mounting: Standard 35mm DIN rail enclosure for easy installation inside your main Distribution Box (DB) or solar AC combiner box.

Why a VA Protector is Mandatory for Pakistani Solar Inverters

Unstable WAPDA/K-Electric voltage fluctuations, sudden neutral wire breakage, and generator changeover spikes are the leading causes of fried solar inverter motherboards and AC control boards. By placing this 63A adjustable protector between your WAPDA meter and solar inverter AC input, your inverter is 100% isolated from high/low voltage spikes, saving you tens of thousands of rupees in inverter repair costs.
