◆ The maximum inclination of the circuit breaker installation is ±22.5°
◆ The circuit breaker can work reliably under earthquake conditions (4g);
◆ The circuit breaker should be installed in a place where there is no danger of explosion, no conductive dust, no corrosion of metal and no damage to insulation.
◆The circuit breaker should be installed in a place where there is no rain or snow.
Classification of Circuit Breaker
• Type A: The N pole is not equipped with an overcurrent release ( Shunt Trip ). The N pole is always on, and it is not switched on/off together with the other three poles.
• Type B: The N pole is not equipped with an overcurrent release ( Shunt Trip ) and is switched on/off together with other three poles (N pole is closed first and then opened).
• Type C: The N pole is installed with an overcurrent release ( Shunt Trip ) , and is switched on/off together with the other three poles (the N pole is off first and then on).
• Type D: N pole is installed with an overcurrent release ( Shunt Trip ) . The N pole is always on, and it is not switched on/off together with other three poles.
