ОПИСАНИЕ ПРОДУКТА
SIEMENS 3WL1106-3BB32-4AN2 Z=S33 - 3-Pole Fixed-Mounted Air Circuit Breaker
This SIEMENS 3WL series air circuit breaker is a 3-pole fixed-mounted device engineered for primary circuit protection in industrial power distribution systems. It integrates an ETU350 electronic trip unit providing LSI (Long-time, Short-time, Instantaneous) protection functions, ensuring precise overload and short-circuit fault interruption. Designed for critical applications requiring robust current interruption and selective coordination, it is suitable for main incomers, feeder protection, and generator protection within switchgear assemblies.
