3WL1225-2DG46-4GA4 SIEMENS

The 3WL1225-2DG46-4GA4 Siemens is a robust and reliable 4-pole withdrawable circuit breaker designed for comprehensive circuit protection and control. Compliant with IEC standards, this size II circuit breaker is engineered to handle a rated current (In) of 2500A at up to 690V AC, operating at 50/60Hz. It boasts a high ultimate short-circuit breaking capacity (Icu) of 66kA at 500V, ensuring effective protection against overcurrents. Featuring a rear connection horizontal configuration, it simplifies installation and maintenance within electrical panels. The integrated ETU 27 overcurrent release provides adjustable LSING protection, allowing fine-tuning of protection settings from 0.4 to 1 times the rated current. Ground fault and neutral protection are integrated, enhancing safety and preventing damage from earth leakage. The circuit breaker is equipped with a motorized/manual operating mechanism, incorporating 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 and a shunt release "F", F1 50/60 Hz 230 V AC/220 V DC with a 100% on-load factor, ensuring reliable remote tripping capabilities. Furthermore, it is configured with 4 normally open (NO) and 4 normally closed (NC) auxiliary contacts for enhanced monitoring and control functionalities.
