Key Features
Product Description
KSZ3 traction fuse adopts hook‑blade mounting structure with ceramic tube housing. It is equipped with 99.99% high‑purity silver fuse element and high‑strength quartz‑sand filling for efficient arc quenching. All contact surfaces are silver‑plated and hardware components are non‑magnetic. Rated voltage 2000VAC, rated current 200A‑450A, breaking capacity up to 120kA. With low pre‑arcing I²t characteristic, it cuts off short‑circuit faults within microseconds, protecting high‑power semiconductors including diodes, thyristors, GTO, IGCT and IGBT. Widely applied for railway traction converters, large rectifiers, inverters, static transfer switches, AC & DC drives and UPS systems. Robust anti‑vibration construction for harsh on‑board conditions. Overall dimension:243×65×62 mm, net weight 1.7kg per piece.
