3WL1116-2CB45-4GA2 SIEMENS

The 3WL1116-2CB45-4GA2 Siemens is a robust and reliable 4-pole withdrawable circuit breaker designed for comprehensive circuit protection in industrial and commercial applications. Compliant with IEC standards, this size I circuit breaker is engineered to handle a rated current (In) of 1600A at up to 690V AC, operating at 50/60Hz. It features a high breaking capacity (Icu) of 55kA at 500V, ensuring effective interruption of fault currents. The rear connection horizontal configuration simplifies installation and maintenance within electrical panels. Equipped with an ETU 25 overcurrent release, it provides adjustable LSI (Long-Short-Instantaneous) protection, customizable from 0.4 to 1 times the rated current. The motorized/manual operating mechanism includes a spring charging motor compatible with AC 50/60 Hz 208-240 V or 220-250 V DC, enhancing operational flexibility. Activation is supported by AC 50/60 Hz 230 V and 220 V DC. It includes a 1st auxiliary release with a shunt release "F", F1 rated for 50/60 Hz 230 V AC/220 V DC with a 100% on-load factor. The breaker is configured with 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, providing additional signaling capabilities.
