suppression and harmonic elimination cabinet; VS1 vacuum circuit
breaker, etc.; substation. The products are sold to all regions of
the country and are widely used in power grids, petrochemicals,
steel, mining, power generation, biological engineering,
large-scale construction projects, and other fields.QUNENG - MMCB
(molded case circuit breaker) series The electronic
plastic-case circuit breaker has four protection functions:
overload long delay, short delay, short instantaneous, and ground
fault. Commonly used, the rated current has the following
types 15 25 30 40 50 60 75 80 100 125 160 200 225 250 315 350 400

typePlastic-case circuit breakers are also known as device circuit
breakers, all parts are sealed in a plastic shell, auxiliary
contacts, Undervoltage release, shunt release, etc., are
modular. Because the structure is very compact, the
plastic-case circuit breaker can not be repaired. Most of them
use manual operation, large capacity can choose electric
closing. Due to the application of electronic overcurrent
release, plastic-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 market share of
class A products using thermal magnetic release is higher. A
plastic-case circuit breaker is the contact, interrupter,
release device, and operating mechanism are installed in a plastic
shell, generally does not consider maintenance, suitable for the
branch protection switch, over current release device has two kinds
of thermal magnetic and electronic, general thermomagnetic
plastic-case circuit breaker is a non-selective circuit breaker,
only overload long delay and short circuit instantaneous two
protection methods. The electronic plastic-case circuit
breaker has four protection functions: overload long delay, short
delay, short instantaneous, and ground fault. Some of the new
products of electronic mold-case circuit breakers also have
regional selective interlocking functions. Most of the molded
case circuit breakers are manually operated, and some have motor
operating mechanisms.FAQQ1: Are you a factory or trading
