MZM2 Series Plastic Shell Circuit Breaker - Low Voltage Electronic Components

Introduction: Circuit Breaker
MZM2 Series Plastic Shell Circuit Breaker (hereinafter refer to the circuit breaker) is a 21st high-tech product. It has advanced design, high performances, pleasing appearance and small volume. It adopts microelectronics technology and intelligent control function. The whole series can achieve “zero flying arc”.
Function and Usage Scope: Circuit Breaker
The circuit breaker applies to AC 50Hz 690V rated voltage and 800A rated current power system. It can protect the circuit against overload, short circuit and lack of voltage. It can control infrequent operations of the electric motor.
Standards: Circuit Breaker
The circuit breaker meets GB14048.2"Low Voltage Switch and Control Devices Low Voltage Circuit Breaker" , IEC60947-2"The Second Part of Low Voltage Switch and Control Devices: Low Voltage Circuit Breaker" and other standards.
Working and Environmen Ctonditions of Circuit Breaker [Low Voltage Electronic Components]
Surrounding air temperature: maximum +4O°C, minimum一5°C
The altitude of the installation site should below 2000m.
Atmospheric relative humidity should below 50% at the maximum temperature +4 O°C. It can be a little higher at lower temperature.  
Maximum relative humidity of the most humid month should not exceed 90% and the minimum temperature of this month should not exceed +25°C with the consideration of the dew on the surface of the product caused by the change of the temperature.
Pollution rank: III
The “1, 3, 5, N1” terminals of the circuit breaker are accessed to the power supply and “2, 4, 6, N2” terminals are accessed to the load circuit. It can not be reversed.
