The difference between PC-class dual power supply and CB-class dual power supply
No matter which company, dual power supply has the difference between PC level and CB level, then what is PC level, what is CB pole? PC level: TSE that can be connected and carried, but not used to break the short-circuit current, that is, there is no short-circuit protection function, and it still switches under short-circuit conditions. Class CB: TSE with overcurrent release, its main contacts can be switched on and used to break short-circuit current. Generally speaking, the CB level, that is, the main circuit switch has a short circuit and overload protection function, so the actuator is usually a miniature circuit breaker and a molded case circuit breaker. TSE: An appliance consisting of one or more devices used to disconnect a load circuit from one source and connect to another source.
