3VL3720-3EJ46-0AA0 SIEMENS

The 3VL3720-3EJ46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It belongs to 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=200A indicates a rated current of 200A, while the adjustable IR setting allows for overload protection within the range of 160A to 200A. For short-circuit protection, the II setting is adjustable between 1000A and 2000A. This model is configured with N unprotected, meaning the neutral conductor is not protected. It does not include an auxiliary release, simplifying the control mechanism. Furthermore, it is designed without an auxiliary/alarm switch, focusing on core circuit protection functions. This circuit breaker is ideal for applications requiring reliable and high-performance protection against overloads and short circuits.
