Germany design circuit breaker 10ka breaking capacity
The state-of-art design
Elegant appearance;cover and handle in arc shape make comfortable operation.
Contact position indicating window
Transparent cover designed to carry label
Handle central-staying function for circuit fault indicating
In case of overload ,to protected circuit,MCB handle trips and stays at central position, which enables a quick solution to the fauity line.The handle cannot stay in such position when operatedmanually.
