3VL5763-3DC36-0AA0 SIEMENS

The 3VL5763-3DC36-0AA0 circuit breaker from Siemens is a robust and reliable 3-pole device designed for line protection in demanding electrical systems. It belongs to the VL630L series, characterized by its very high breaking capacity, specifically an ultimate short-circuit breaking capacity (Icu) of 100kA at 415V AC. This circuit breaker is equipped with a TM trip unit, offering comprehensive protection features. The rated current (In) is 630A, while the overload protection (IR) can be adjusted between 500A and 630A, providing flexibility for various load requirements. For short-circuit protection, the instantaneous tripping current (II) is adjustable from 3250A to 6500A. This allows for precise coordination with downstream devices. The breaker is designed without an auxiliary release and lacks auxiliary/alarm switches, simplifying its installation and operation. It ensures reliable interruption of overloads and short circuits, safeguarding electrical equipment and preventing costly downtime. Its high breaking capacity makes it suitable for applications where high fault currents are expected.
