Plastic shell type circuit breaker is a mechanical switching appliance, which is mainly used to connect, carry and break the current under normal circuit conditions, but also to connect and carry a certain time and break the current under specified abnormal circuit conditions. This type of circuit breaker has the following characteristics and uses:
Purpose: plastic shell type circuit breaker (MCCB) is used to distribute electrical energy and protect the line and power equipment from overload, short circuit, undervoltage and other faults. They are also used for motor infrequent starting and overload, short circuit, undervoltage protection
Technical parameters: the rated working voltage of MCCB is
AC400V, rated insulation voltage is AC500V, rated impulse voltage is 8kV. They are able to accommodate frequencies of 50/60Hz and have a pole number of 3P
Protection function: Plastic-case circuit breaker has overload long delay, short circuit instantaneous two-stage protection function, can also be used with leakage, measurement, electrical operation and other module units. They are often used as terminal switches or branch switches in low-voltage distribution systems, replacing the past fuse and knife switch
Design and purchase: In the purchase of plastic-case circuit breaker, should consider the development of product design and purchase focus, including personal safety, the protection of electrical lines and equipment and reliable, uninterrupted power supply. In addition, it is also necessary to pay attention to the breaking capacity indicators of the circuit breaker, such as the rated limit short-circuit breaking capacity Icu and rated operation short-circuit breaking capacity Ics
Conditions of use: Plastic-case DC circuit breaker is suitable for rated voltage DC250V~DC1000V, rated current 10A~1250A DC power grid circuit. They have fast closing and fast breaking function, compact structure, small size, easy to use .
In summary, plastic shell circuit breaker is a kind of multi-functional, high-efficiency electrical protection equipment, widely used in low-voltage distribution system and motor protection, to provide overload, short circuit and undervoltage protection for circuits and equipment.
