CNC Ycw3-2000 Series Air Circuit Breaker

CNC Ycw3-2000 Series Air Circuit BreakerProduct DescriptionYCW3 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.Breaking capacity Rated current In(A)16002000320040006300Rated ultimate short circuit breaking capacity Icu(kA)400/415V6580100120135660/690V50658585100Rated service short circuit breaking capacity Ics(kA)400/415V556580100135660/690V42657085100Rated short time withstand current Icw.1s(kA)400/415V506580100135660/690V42657085100Rated short circuit making and breaking capacity Icm(kA)400/415V110176220264297660/690V77143154187220Electric life80008000800060001500Mechanical life (Maintenance)300003000020000200005000Mechanical life (Non-maintenance)200001500012500100002500Dimension(mm) W×H×LDrawout type3P285×345×351375×451×432435×486×439435×486×439930×486×4394P352×345×351470×451×432550×486×439550×486×439/Fixed type3P254×251×320362×362×395426×378×395426×378×395/4P324×251×320457×362×395537×378×395537×378×395/Note: 6300A only has 3P drawout typeCompany Profile
