DC circuit breaker refers to the circuit breaker used in the DC power distribution system.It is generally suitable for solar photovoltaic power generation and power distribution systems, battery energy storage systems, new energy vehicle DC charging systems, etc.
The input power terminal of the circuit breaker is a system of DC current.
Generally, DC circuit breakers include DC micro -circuit breakers (MCB), DC plastic shell circuit breaker (MCCB) and B type RCD (Residual Current Device).
DC circuit breaker MCB (DC micro -circuit breaker)
DC micro -circuit breaker MCB is designed for DC (DC) circuit application, which is used for overcurrent and short circuit protection of electrical or electrical equipment.
DC micro -broken circuit breakers are the same as AC micro -broken circuit breakers.The use scenario of AC MCB and DC MCB is different.
DCB MCB is mostly used for DC (DC) system applications, such as new energy, solar photovoltaic (PV) and solar battery energy storage systems.The voltage status of DC MCB is generally DC 12V-1500V.
The difference between AC micro -circuit breakers and DC micro -circuit breakers in product physical parameters.
The AC MCB is marked with LOAD and LINE on the product, and the DC road cutter symbol is marked as a current (+), negative (-) and product direction direction.
DC plastic shell circuit breaker (DC plastic shell railway)
DC plastic shell circuit breaker (DC plastic shell circuit breaker) is an ideal choice for energy storage, transportation and industrial DC circuits.
DC plastic shell circuit breaker functions are the same as AC plastic -shell circuit breakers, and have overloading and short -circuit protection functions for large current power distribution systems.
They are also used for non -ground battery supply circuits, for emergency backup and backup power.In the grounding photovoltaic system in the solar device, the DC MOLDED CARCUIT BREAKER uses the DC Molded Circuit Breaker in the grounding photovoltaic system. Application engineering and review ensure the protection requirements.
DC MCCB (DC MCCB, DC MOLD CARCUIT BREART) is a circuit control protection device for energy storage, transportation and industrial DC circuits.They are also used to provide unmoving battery power circuits to provide emergency spare power and backup power.Chanan produces high -voltage DC circuit breakers. Chanan DC plastic shell switch can provide up to 1 25-400,1000V -1500 V DC.
Can I use AC circuit breakers to change the DC circuit breaker?
AC current signals are constantly changing its value every second.The circuit breaker arc is extinguished at 0 volts, and the protection circuit is not affected by large currents.
But the DC signal is not communicated. It works in a constant state. Electrician Manuo Facturer of DC Molded Case Circuit Breaker Value will only change when the circuit checkspoint or the circuit is reduced to the ManuFacturr of DC Molded Circuit Breaker.
