Electronic Plastic Case Busbar Circuit Breaker MCCB at factory price
Advantages of Busbar type molded case circuit breaker.
1. The Design of busbar protection against electric shock;The busbar shell is protected by all sides and the personnel can be assured of live operation. It can also eliminate the earth fault caused by external damp dust and foreign objects. The busbar adopts phase closed structure so as to prevent the occurrence of alternate short circuit.
2. Go down the internal temperature rise in the complete cabinetThe busbar connection row is integrated with the circuit breaker, This structure reduces the quantity of connection points of the transition row and then the connection points go down the temperature by 20%, and finally decrease sharply the internal temperature rise of the complete set.
3. Standardized installationThe frame space between busbars is 45mm, which can save 30% of busbar connection materials, reduce the installation volume by 20%, and improve the installation efficiency by 60%.
4. Zero arcing distanceThe product adopts a new high-score breaking structure design, which involves the arc extinguishing structure system, the air flow channel system, and the comprehensive improvement of the arc isolation structure to realize the zero arcing distance.
Product Description
Busbar type circuit breaker is the most important product , with two series of molded case circuit breakers, independently developed.
Thermal magnetic type circuit breakers have four frames: 125, 320, 400 and 630 frame,and current range : 16A-630A; breaking capacity is: Icu=70/50kA, Ics=50/35kA.
The intelligent molded case circuit breaker have four frames: 125, 320, 400 and 630 frame, and current range: 16A-630A; breaking capacity is: lcu=70/50kA,1cs=50/35kA;
This series realizes human-machinedepression, online test fault record download and other functions.
