/Conditions for use of earth leakage circuit breaker molded case circuit breaker
The altitude of the installation site shall not exceed.
Ambient air temperature The upper limit of the ambient air temperature does not exceed +°C. The average value of the ambient air temperature does not exceed +°C. The lower limit of the ambient air temperature does not exceed +°C.
Atmospheric conditions: The relative humidity of the atmosphere does not exceed +°C when the ambient air temperature is +°C. It can have higher relative humidity at lower temperatures. When the monthly average minimum temperature of the wettest month does not exceed +°C, the monthly average relative humidity does not exceed +°C. The monthly average maximum relative humidity is, taking into account condensation that occurs on the product surface due to temperature changes.
Installation conditions: Install in a place without shock, vibration, rain or snow. The upper terminal is connected to the power supply side and the lower terminal is connected to the load side. The inclination with the vertical plane does not exceed the inclination.
Structural features of molded case circuit breaker
It is mainly composed of contacts, operating mechanism, hydraulic electromagnetic release, arc extinguishing mechanism and machine charging shell. When the protected circuit or motor occurs an overload short circuit , the circuit breaker can reliably break. Multi-pole circuit breakers can be linked together. If an overload occurs on an important pole, all poles can be broken simultaneously.
Molded case circuit breakers are used in circuits with AC, rated current from to, rated insulation voltage, rated working voltage and below. The circuit breaker can be used for infrequent switching of lines and infrequent starting of motors respectively. It is used to distribute electric energy in power distribution networks and serve as overload, short circuit and under-voltage protection for lines and power equipment.
Conditions of use
Ambient air temperature The ambient air temperature does not exceed +℃, and the average temperature value within it does not exceed +℃. The lower limit of the ambient air temperature is ℃.
The altitude of the installation site should not exceed .
When the maximum air temperature is +℃, the relative humidity of the air does not exceed the allowable higher relative humidity at lower temperatures.
Dye level.
Installation category III.
Installation conditions The circuit breaker should be installed in a place where there is no rain or snow attack and no significant shaking and impact vibration. The circuit breaker should generally be installed vertically.
Series plastic case circuit breakers are suitable for distribution networks with AC, rated operating voltage up to, and rated current up to, used to distribute electric energy and protect circuits and power supply equipment from overload, undervoltage and short-circuit protection. And it is used for infrequently breaking and connecting lines under normal working conditions.
