breakers Mini circuit breakerMolded case circuit breakers are also
called device circuit breakers. All parts are sealed in plastic
casings. Auxiliary contacts, undervoltage releases and shunt
releases are mostly modularized. Due to the very compact structure,
molded case circuit breakers are basically impossible to repair.
Most of them are manually operated, and electric opening and
closing can be selected for large capacity. Due to the application
of electronic overcurrent releases, molded case circuit breakers
can also be divided into Class A and Class B. Class B has good
three-stage protection characteristics, but due to price factors,
the use of thermal magnetic releases Class A products have a higher
market share. The molded case circuit breaker is to install the
contacts, arc extinguishing chamber, release and operating
mechanism in a plastic shell. Generally, maintenance is not
considered. It is suitable for the protection switch of the branch
circuit. The over-current release has thermal magnetic Generally,
thermal magnetic molded case circuit breakers are non-selective
circuit breakers, which only have two protection modes: overload
long time delay and short circuit instantaneous. Electronic molded
case circuit breakers have overload long time delay, short circuit
short Four protection functions of time delay, short circuit
instantaneous and ground fault. Some newly launched products of
electronic molded case circuit breakers also have regional
selective interlocking functions. Most molded case circuit breakers
are manually operated, and some have motor operating mechanisms.
