3VL4720-3EM46-0AA0 SIEMENS

The 3VL4720-3EM46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL400L series, known for its very high breaking capacity, specifically an Icu of 100kA at 415V AC. This circuit breaker features a TM trip unit, providing reliable overload and short-circuit protection. The In rated current is 200A, with an adjustable overload protection range (IR) from 160A to 200A. The short-circuit protection (II) is also adjustable, ranging from 1000A to 2000A. Notably, the neutral conductor is protected at 100%. This model does not include an auxiliary release or auxiliary/alarm switch, focusing on core protection functionalities. It ensures the safety and reliability of electrical installations by quickly interrupting circuits in the event of overloads or short circuits. Siemens' commitment to quality and performance is evident in the design and capabilities of this circuit breaker.
