The SVG/F 63A Single-Phase Voltage and Current Protection Relay, developed by Borna Electronics, represents the latest generation of high-current protection devices for single-phase electrical systems. Designed for residential, commercial, office, and industrial applications, the relay provides comprehensive protection against overvoltage, undervoltage, overcurrent, phase-loss conditions, and repetitive power interruptions.
The device features dedicated voltage and current displays that continuously show real-time operating values. During timing operations, the displays also indicate the remaining trip and reconnection delay times, providing clear system status information. With adjustable voltage and current thresholds and a 63 A output rating, the SVG/F is ideal for protecting high-power loads up to 12 kW.
