Our Advantages

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 protect 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.

High short-circuit capacity
High short-circuit capacity 4.5kA for whole range and 10kA capacity for current rating up to 63A thanks to the powerful electric arc extinguishing system.
Long electrical endurance up to 6000 cycles thanks to quick making mechanism.

Handle padlock device
MCB handle can be locked either at “ON” position or at “OFF” position to prevent unwanted operation of the product.

Screw terminal lock device
The lock device prevents unwanted or casual dismounting of connected terminals.
