3WL1116-2DG45-4GN4 SIEMENS

The 3WL1116-2DG45-4GN4 Siemens is a robust and reliable 4-pole withdrawable circuit breaker designed for comprehensive circuit protection and control. Compliant with IEC standards, this size I circuit breaker is engineered to handle a rated current (In) of 1600A at up to 690V AC, making it suitable for demanding industrial applications. It operates at 50/60Hz and offers a high ultimate short-circuit breaking capacity (Icu) of 55kA at 500V, ensuring effective protection against overcurrents. The rear connection is horizontally oriented for streamlined installation within electrical panels. Equipped with an ETU 27 overcurrent release, it provides adjustable LSING protection, allowing precise customization of protection settings from 0.4 to 1 times the rated current. Integrated ground fault and neutral (N) protection further enhance safety and prevent damage from earth leakage currents. The circuit breaker features a motorized/manual operating mechanism with a spring charging motor, compatible with AC 50/60 Hz 208-240 V or 220-250 V DC. 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 operating at 50/60 Hz 230 V AC/220 V DC with a 100% on-load factor, along with a 2nd auxiliary release "R", F3 undervoltage release, instant. 208-240 V AC, 220-250 V DC and 4NO+4NC contacts for versatile signaling and control capabilities.
