The universal circuit breaker manufacturer cannot close the breaker due to an under-voltage release, if the voltage is too low or the under-voltage release coil loses power, the universal circuit breaker will trip and cannot be re-closed. Universal circuit breaker can not be manually closed when not energized.

Because the universal circuit breaker has a loss of voltage decoupling function, universal circuit breaker manufacturers that is, when the power supply voltage is reduced or lost, the switch will automatically decouple. Therefore, when there is no electricity on the power side of the switch, it cannot be closed. The circuit breaker is arranged in three dimensions, with the contact system, instantaneous overcurrent decoupler left and right side plates mounted on an insulated plate. The upper part is equipped with an arc extinguishing system and the operating mechanism can be mounted on the front or on the right side.

Operating environment 

1、The upper limit of ambient air temperature shall not exceed +40℃, the lower limit shall not be lower than -5℃, and the average value of 24h shall not exceed +35℃.

2、The altitude of the installation site shall not exceed 2000m. 

3. The relative humidity of the atmosphere does not exceed 50% at an ambient air temperature of +40°C; it can have a high relative humidity at a lower temperature; the average maximum relative humidity for the wettest month is 90% and the average monthly relative humidity is 90%. The average minimum temperature is +25°C and takes into account condensation on the product surface due to temperature variations.
