DIFFERENT BETWEEN FUSE AND CIRCUIRBREAKER:
Different protection methods
The fuse is protected by fusing. After the fault is eliminated, the fuse needs to be replaced again before the power supply can be restored. Therefore, it is not convenient for maintenance.
The protection mode of the circuit breaker adopts the tripping form. After troubleshooting, the normal power supply can be restored only by closing action, so it will be much more convenient than the fuse in terms of maintenance and recovery.
Different action speed
The fusing speed of the fuse can reach microseconds锛?渭 s) Level, that is to say, its speed is much faster than that of circuit breaker. This capability is usually suitable for installation in occasions with similar requirements for fast cut-off.
The tripping action speed of the circuit breaker is in milliseconds (MS), which can be seen that it is much slower than the fuse, so it can only be used in occasions where the requirements for cut-off speed are not very high.
What is PV MCB & How to work?
PV MCB can be used to solar system uses DC power, and it can also be used to protect main circuits such as inverters and photovoltaic battery packs.
