Inquire
An under-voltage / over-voltage tripper is useful for protection against voltage dips and swells. Once supply recovers to normal, only then can the breaker be turned ON. This accessory provides a cost-effective and easy way to implement this solution.
1. Protection of the load in the event of a voltage drop (between 70% and 35% of its rated value)
2. Positive safety (device's tripping when the voltage is disconnected) emergency stop by means of a button.
3. To be mounted on the left side of the MCBs/RCBOs thanks to the special pin.
