There are significant differences between DC miniature circuit breakers and AC miniature circuit breakers in many aspects, mainly including:
How it works:
Dc miniature circuit breaker is mainly suitable for direct current circuit. Its working principle is usually to disconnect the circuit through the fuse, when the current flow in the circuit is large, the fuse will be heated and melted, thus interrupting the circuit.
Ac miniature circuit breaker is suitable for AC circuit. Its working principle is mainly through the magnetic trigger, the current through the coil into a magnetic field, so as to push the iron core to trigger the switch, so that the circuit can be disconnected.
Protection level:
Because the working environment of the DC circuit is different from that of the AC circuit, the DC miniature circuit breaker needs to be higher than the AC circuit breaker in terms of protection level. Under normal circumstances, DC small circuit breakers need to reach the protection level of IP67.
Ac circuit breakers usually only need to reach the IP54 level of protection.
Application field:
Because of its excellent performance in the DC circuit, DC mini-circuit breakers are usually widely used in scenarios that require DC power protection, such as some specific industrial control systems and communication equipment.
Ac mini-circuit breakers are more commonly found in everyday AC power system protection, such as circuit protection in homes, offices and commercial buildings.
In addition, the two may also be different in terms of structure, contact material, arc extinguishing measures, etc., to meet the special needs of their respective working environments.
In general, there are significant differences between DC miniature circuit breakers and AC miniature circuit breakers in terms of working principle, protection level and application field. When choosing which circuit breaker to use, factors such as circuit type, working environment and protection needs should be fully considered.
