Note: 1) According to GB14048.1, the term "lifespan" refers to the probability of the number of operational cycles completed by an electrical appliance before repairing or replacing a component. 2) Select zero arcing covers with heights of 6mm (CM3L-100), 7.5mm (CM3L-225), 9.3mm (CM3L-400), and 9.5mm (CM3L-630) respectively to achieve zero arcing. 3) When this series of three pole circuit breakers is connected to three-phase loads, the load cannot have a neutral wire, including the power supply of the load control circuit taken from the load end of the circuit breaker, which cannot have a neutral wire, otherwise the circuit breaker will malfunction. 4) When this series of three pole and four pole circuit breakers are connected to single-phase loads, the phase line should be connected to the A pole, the neutral line to the C pole, and not to the B pole.
