An MCB (miniature circuit breaker) or DC MCB is a switch that closes, carries, and breaks a circuit. It can open the circuit if the circuit current exceeds a certain threshold. You can usually use an isolator with a fuse in place of miniature circuit breakers.
An MCB is a switch that changes fault current or carries rated current. When the circuit current exceeds a defined amount or limit, these devices can automatically cut the circuit. You can manually switch on or off the MCB like standard switches whenever necessary.
C type MCB
This type of MCB is designed to trip at 5 to 10 times of rated current. These MCBs are usually used for high inductive loads where switching surges are high such as in fluorescent lighting and small motors. So, they are suitable for industrial and highly inductive commercial installations.
Warm Tips:
Pay attention to polarity.
Select wire size according to rated current.
Fast closing to ensure load operation and prolong service life.
The shell is made of PBT plastic, the cover is made of transparent PC, the sealing ring is made of silicon rubber, and the guide rail is made of tin plate.
Application: Wide range of use, suitable for installation indoors, widely used in solar panel, PV, RV, homes, workshops, hotels, shopping malls, power stations, etc.
This DC circuit breaker has no polarity requirement in use, and the positive and negative poles can be inverted. However, the installation, use, and maintenance of DC circuits are based on polarity requirements. So, in order to provide reliable indication and reference for the distribution, we highly recommend that you connect the wires according to the marked polarity.
