3VL5750-3EC46-0AA0 SIEMENS

The 3VL5750-3EC46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL630L series, known for its very high breaking capacity, specifically an ultimate short-circuit breaking capacity (Icu) of 100kA at 415V AC. The breaker features a thermal-magnetic (TM) trip unit, providing comprehensive protection against overloads and short circuits. The rated current (In) is 500A, with an adjustable overload protection range (IR) from 400A to 500A, allowing for fine-tuning to specific load requirements. The instantaneous short-circuit protection (II) is also adjustable, ranging from 2500A to 5000A, ensuring rapid response to fault currents. This model offers N-pole protection, enhancing safety and reliability. It is configured without an auxiliary release and does not include auxiliary or alarm switches, simplifying installation and reducing potential points of failure. This circuit breaker is ideal for applications demanding high performance and reliable protection against electrical faults. Its adjustable settings and high breaking capacity make it suitable for a wide range of industrial and commercial settings.
