3VL2712-3EM43-0AA0 SIEMENS

The 3VL2712-3EM43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL160L series, known for its very high breaking capacity, with an Icu of 100kA at 415V AC. This circuit breaker features a TM (Thermal-Magnetic) trip unit, providing reliable overload and short-circuit protection. The In (rated current) is 125A, while the Ir (adjustable rated current) can be set between 100A and 125A for overload protection. The II setting, ranging from 625A to 1250A, handles short-circuit protection. Notably, this model offers N (neutral) protection at 100%, ensuring comprehensive circuit safeguarding. It does not include an auxiliary release, simplifying the design and installation. Furthermore, it is configured without an auxiliary/alarm switch, focusing on core circuit protection functions. This circuit breaker is ideal for applications requiring high breaking capacity and adjustable protection settings.
