Ycw3 Series 200A-6300A 3p 4p Acb Drawout/Fixed Intelligent Controller Air Circuit Breaker

 Product DescriptionGeneralYCW3 series air circuit breaker(hereinafter called ACB) is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current between 200A and 6300A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single phase earthing fault.With intelligent and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines(for 690V) and modern high-buildings, especially for the distribution system of intelligentized building.Standard: IEC/EN 60947-2.     1.Rated current in scope of frame size 1600 Type In: 200A,400A,630A,800A,1000A,1250A,1600A 2000 Type In: 630A,800A,1000A,1250A,1600A,2000A 3200 Type In: 2000A,2500A,3200A 4000 Type In: 2500A,3200A,4000A 6300 Type In: 4000A,5000A,6300A 2.Number of poles 3-default 4-4 pole 3.Installation Fixed type-horizontal, vertical Drawout type-horizontal, vertical 4.Intelligent controller M type 2M type: digital display, over-current protection (overload, short delay, instantaneous), 4P or 3P+N have earthing protection. 3M type: LCD display, over-current protection(overload, short delay, instantaneous), 4P or 3P+N have earthing protection.
