Audited Supplier Construction and Feature
1.The state-of-art design
1.1Elegant appearance; cover and handle in arc shape make comfortable operation.Contact position indicating window.Transparent
1.2cover designed to carry label.
2.Handle central-staying function for circuit fault indicating
2.1In 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 operatedmanually.
3.High short-circuit capacity
3.1High short-circuit capacity 10KA for whole range and 15kA capacity for current rating up to 40A thanks to the powerful electric
arc extinguishing system.Long electrical endurance up to 6000 cycles thanks to quick making mechanism.
4.Handle padlock device
4.1MCB handle can be locked either at "ON" position or at"OFF" position to prevent unwanted operation of the product.
5.Screw terminal lock device
5.1The lock device prevents unwanted or casual dismounting of connected terminals.
