1. 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. |
2. 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 faulty line. The handle cannot stay in such position when operated manually. |
3. Handle padlock device. |
MCB handle can be locked either at "ON" position or at "OFF" position to prevent unwanted operation of the product. |
