The SVP-916 63A Automatic Voltage and Current Protection Relay is designed to protect single-phase electrical equipment against overvoltage, undervoltage, and overcurrent conditions.
The device continuously monitors the electrical supply and automatically disconnects the connected load when voltage or current exceeds the configured protection limits. Once normal operating conditions are restored, the relay can automatically reconnect the power supply after an adjustable recovery delay.
Featuring a dual digital LED display, adjustable protection thresholds, automatic recovery, and 63A rated current, the SVP-916 is suitable for residential distribution boards, commercial installations, and electrical control panels.

Protection Functions
1. Overvoltage Protection
Automatically disconnects the electrical load when the supply voltage exceeds the configured upper limit.
2. Undervoltage Protection
Disconnects connected equipment when the incoming voltage drops below the configured minimum level.
3. Overcurrent Protection
Monitors the load current and disconnects the output when the current exceeds the selected protection threshold.
4. Automatic Recovery
Automatically restores the electrical supply when voltage and current return to acceptable operating conditions, according to the configured reset and recovery settings.
5. Adjustable Protection Timing
Allows configuration of protection response times and reconnection delays to suit different electrical applications.
