Breaking capacity Icn
1P, 2P, 3P, 4P
•Elegant appearance; cover and handle in arc shape make comfortable operation.
•Contact position indicating window
•Transparent cover designed to carry label
•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 operated manually.
•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
Tripping Curve( MCB circuit breaker ):
Curve B: (3~5 In) protect and control circuit against overload and short circuit; protect people and length cables in TN and IT systems.
Curve C:(5~10 In) protect and control circuit against overload and short circuit; protect resistive and inductive loads with low inrush current.
CurveD: (10~20 In) protect and control circuit against overload and short circuit; protect circuits which supply loads with high inrush current when the circuit closing.
