Voltage Display MCB breaker Protector AC230V, Undervoltage and Overvoltage Protection Switch, Din Rail Voltage Protector



Intelligent Self-resettable Overvoltage and Undervoltage Protection Device shows features as following:

- Product shape is compatible with the miniature circuit breakers;


- Small size, large switching power, max. current is 63A;


- Embedded high-performance MCU specialty chip to ensure accurate and precise measurement of voltage.


- Saving power because its circuit breaker switch is made by Instantaneous pulse- driving coil;


- Large magnetic latching strength; Vibration resistance; Small contact resistance, low power consumption and reliable performance;


- Optimized circuit design to realize real micro function;


  • The protection device will break the circuit when single-phase line is under overvoltage or undervoltage; Without manual operation, the protection device will automatically reset to connect the circuit after single-phase voltage returns to the normal delay value. The protection device will not malfunction when the circuit is under instant or temporary overvoltage.
  • The protection device will not be damaged itself if the fault voltage of the circuit reaches the highest value.
  • Voltage protection range: Normal type of 40A and below: 0~450V Intelligent type of 50/63A: 0~600V
  • Withstand impulse voltage: 4kv (Compliance with electrical safety standards Ⅲ class)
  • The LED with double color on the panel indicate the working status of the protection device. When the indicator light is green, the power is supplied normally. When the indicator light is red, the power is cutted off. 
  • Modular design of product appearance following the 2.5P and 2P Standard Modules; Din-rail mounting for installation.
  • Connection capacity: insulated wire of 16 mm2 and below .
  • Power of the intelligent type should be larger than 0.9.
