CJMD16-63 1-4p 250V-1000V 10ka DC MCB Miniature Circuit Breaker

Short Description:

·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.
