What is the Definition of a Miniature Circuit Breaker?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.The Functioning Principle of the DC MCBAn 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.About this
itemSpecifications:Rated current: 63A; Rated voltage is 500V;
Breaking capacity is 6KA; Number of levels: 2 poles.Powerful
Protection: Fast trip to ensure reliable operation of the load and
prolong the life of dc circuit breakers.ARC EXTINGUISHING:DC
breaker is more powerful than AC breaker to extinguish arcs. It
means that our low-voltage breaker can be used at the same level
voltage of DC and AC circuit systemAPPLICATION:Used in DC power
system, ship electric power system, solar photovoltaic system, or
other DC system.INSTALLATION: Screw clamp wires, 35mm DIN rail
mountC type MCBThis 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.LEEYEE
Miniature Circuit Breaker MCBWarm 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. Polarity MarkedThis 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.SpecificationsProduct typeDC Miniature Circuit
