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.
