3VL3725-3EJ46-0AA0 SIEMENS

The 3VL3725-3EJ46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL250L series, known for its very high breaking capacity, specifically an Icu of 100kA at 415V AC. This circuit breaker features an Electronic Trip Unit TM, providing advanced protection and control capabilities. The In (rated current) is 250A, while the adjustable IR (overload protection) ranges from 200 to 250A, allowing for customization based on specific load requirements. For short-circuit protection, the II setting is adjustable from 1200 to 2500A, ensuring rapid response to fault currents. This model is designed with N (neutral) unprotected configuration. It does not include an auxiliary release, simplifying the design and reducing potential points of failure. Furthermore, it is supplied without auxiliary or alarm switches, making it suitable for applications where remote signaling is not required. Siemens 3VL circuit breakers provide reliable and effective protection for electrical circuits.
