3phase 4wire self resettable over and undervoltage protector JGGQ-100S

3phase 4wire self resettable over and undervoltage protector adopts high-speed micro-low-power processor as the core of the control circuit, magnetic latching relay as the main circuit, and modularized standard design, when the power supply line has overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact, so as to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal electrical appliances in the case of unattended.

1. Introduction

3phase 4wire self resettable over and undervoltage protector When the power supply line has overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal electrical appliances in the unattended situation.
