DIN Rail Over And Under Voltage Protector Relay with 63A Current Limit
Protect connected equipment against selected voltage and current conditions with this TOMZN DIN rail over and under voltage protector relay. It monitors AC voltage and current, and its protection functions can be enabled or disabled to suit your setup.
Use it as a normal switch or cycle switch, and choose manual or automatic reconnection. Adjustable delay-on and delay-off times give you control over how the relay responds in your electrical installation.
Benefits & tips
- Choose your protections: Over-current, overvoltage and undervoltage protection can each be disabled independently.
- Set the timing: Adjust active time and switching delays to match your intended use.
- Check consumption: Optional backlight modes support different viewing preferences, while built-in electricity metering has Class 1 accuracy.
