Construction and Feature

● 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 faulty line. The handle cannot stay in such position when operatedmanually.

● 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.

● 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.
