The maximum of interrupting capacity of CB1 is also considered as the constraint of SCC during simulation.
This new product is designed to provide users with years of safe and reliable service by combining a long life span in mechanical and electrical operation mode with high interrupting capacity to provide selectivity and reduce hazards.
The interrupting capacity from 25 to 150 kA allows a single unit to address multiple applications, which helps reduce product stocking.
* A 65-kiloamp interrupting capacity fault-current rating and testing to 160 kiloamps 8/20 ps per IEC 61643-1.
Because it only offers overload protection and low interrupting capacity, it normally is not used as a replacement for a circuit breaker, but as a glass fuse replacement.
Improvements in the arc-interruption system, for example, increase interrupting capacity and minimize space requirements.
