MZM2 series plastic shell circuit breaker
Purpose and scope of use
This circuit breaker is suitable for power systems with AC 50Hz, rated voltage up to 690V, and rated current up to 800A to avoid the hazards of overload, short circuit, undervoltage, and other faults. It can also be used to control infrequent operation of motors.
meet the standard
The circuit breaker complies with standards such as GB14048.2 "Low voltage switchgear and control equipment - Low voltage circuit breakers" and IEC60947-2 "Low voltage switchgear and control equipment - Part 2: Low voltage circuit breakers".
Working and environmental conditions
Circuit breakers are suitable for the following working environments
The ambient air temperature should not exceed+40 ℃. And below one ℃.
The altitude shall not exceed 2000m.
The relative humidity of the air should not exceed 50% at a maximum temperature of+40 ℃, and higher relative humidity is allowed at lower temperatures. The average minimum temperature of the wettest month should not exceed+25 ℃.
The monthly average maximum relative humidity for that month shall not exceed 90%.
Pollution level: Level 3. There is no explosion hazard in the surrounding air, and there are no corrosive metals, insulation damaging gases, or conductive dust.
The installation category is I-I.
The "1, 3, 5, N1" terminals of the circuit breaker are connected to the power supply, and the "2, 4, 6, N2" terminals are connected to the load and cannot be reversed.
