Selection Guide:
①The single-pole circuit breaker individually controls the on-off of the live wire, which is suitable for 220V lighting circuit.
②The double-pole circuit breaker can simultaneously control the on-off of the live wire and the neutral wire, which is suitable for 220V socket circuit with leakage protection.
③The three-pole circuit breaker can simultaneously control the three-phase 380V three-phase live wire in the circuit.
④The four-pole circuit breaker can simultaneously control three-phase 380V three-phase live wire and a set of neutral wires, which is suitable for controlling industrial power plant circuits.
⑤The single-pole + N does not disconnect the neutral line and only disconnects the live line, which is suitable for situations where the neutral line cannot be disconnected.

Instruction:
①DZ47 series miniature circuit breakers are mainly used for AC 50-60Hz.
②The rated voltage is 400V, which can protect against overload and short circuit in the corresponding current range.
③The electrical devices and lighting circuits can be switched on and off infrequently under normal conditions.
④It is not suitable for direct protection of high inductive and high capacitive loads (such as motors, capacitors and or electric heating equipment).
⑤The wire diameter and the rated current of the circuit breaker need to be selected according to the actual power used.
⑥Since there's no manual, professional installation is highly recommended or you can refer to the universal wiring diagram.
