The 3WL1116-2DG45-4GA4 Siemens is a withdrawable circuit breaker designed for robust circuit protection and control. This 4-pole circuit breaker, conforming to IEC standards, boasts a rated current (In) of 1600A, suitable for systems up to 690V AC at 50/60Hz. It features a size I frame and a rear connection with horizontal orientation for streamlined installation. The circuit breaker's ultimate breaking capacity (Icu) is 55kA at 500V, ensuring reliable interruption of high fault currents. Equipped with an ETU 27 overcurrent release, it provides adjustable LSING protection with settings ranging from 0.4 to 1 times the rated current. Integrated ground fault and neutral protection enhance safety and prevent damage from earth leakage. The motorized/manual operating mechanism includes a spring charging motor compatible with AC 50/60 Hz 208-240 V or 220-250 V DC, activated by AC 50/60 Hz 230 V or 220 V DC. It comes with a 1st auxiliary release and a shunt release "F", F1 rated for 50/60 Hz 230 V AC/220 V DC with a 100% on-load factor. The breaker includes 4 normally open (NO) and 4 normally closed (NC) auxiliary contacts, but does not include a 2nd auxiliary release.
