3VL4720-3EJ46-0AA0 SIEMENS

The 3VL4720-3EJ46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It belongs to the VL400L series, known for its very high breaking capacity, specifically Icu=100kA at 415V AC. This circuit breaker is equipped with an Electronic Trip Unit TM, providing advanced protection features. The rated current (In) is 200A, with an adjustable overload protection range (IR) from 160A to 200A. For short-circuit protection, the instantaneous tripping current (II) can be set between 1000A and 2000A. Notably, this model does not include N-conductor protection, auxiliary release, or auxiliary/alarm switches. It ensures reliable and efficient circuit protection in demanding industrial applications. Its high breaking capacity makes it suitable for environments where high fault currents are anticipated. The electronic trip unit allows for precise adjustment of protection parameters, enhancing system safety and minimizing downtime.
