Wind Energy

Value of the Solution

The disconnector-fuse unit combines load isolation and current limiting, achieving up to 100kA at 400V and providing full overload and short-circuit protection. Its contactor uses a rolling-insertion design to reduce welding risk under high current and improve reliability in wind power applications. The molded-case circuit breaker is compact with high breaking capacity: the 160A frame reaches 70kA at 400VAC while maintaining a short arcing distance to minimize impact on nearby equipment. The AC contactor covers 9–95A rated current and supports flexible accessories; with a surge suppression module on the control coil, it withstands 60–120% Uc voltage fluctuations. The motor protection circuit breaker provides overload, short-circuit, and three-phase unbalance protection. Differential sensing improves phase-loss accuracy, and temperature compensation ensures precise thermal tripping across a wide operating range of -30°C to 70°C.
