3WL1112-2DG36-1AA2 SIEMENS

The 3WL1112-2DG36-1AA2 Siemens is a robust and reliable 3-pole withdrawable circuit breaker designed for comprehensive circuit protection. Compliant with IEC standards, this size I breaker is engineered to handle a rated current (In) of 1250A at voltages up to 690V AC, operating at 50/60Hz. It boasts a high ultimate short-circuit breaking capacity (Icu) of 55kA at 500V, ensuring effective protection against overcurrents. Featuring a rear horizontal connection, it simplifies installation and integration into existing power distribution systems. The integrated ETU 27 overcurrent release provides adjustable LSING protection, allowing fine-tuning of protection parameters within a range of 0.4 to 1 times the rated current. Ground fault and neutral protection are integrated, enhancing safety and preventing damage from earth leakage. Equipped with a manual operating mechanism and energy storage, it ensures reliable operation even in the absence of power. This model includes a mechanical request function, providing added control and monitoring capabilities. It comes standard with 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts for signaling and control purposes.
