Construction and Features
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.Handel central-staying function for circuit fault indicating
Incase 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.High short-circuit capacity
High short-circuit capacity 10kA for whole range and 15kA capacity for current rating up to 40A thanks to the powerful electric arc extinguishing system
4.Handle padlock device
MCB handle can be locked either at “ON” position or at “OFF” position to prevent unwanted operation of the product.
5.Screw terminal lock device
The lock device prevents unwanted or casual dismounting of connected terminals.
