Enclosed automatic transfer switch OXB630 630A 3-pole

The OXB630E3S3Q54B is an enclosed automatic transfer switch (ATS) designed for critical power applications requiring reliability and robust performance. This model features a Level 3 LCD controller integrated directly into the unit, making it suitable for seamless monitoring and operation without additional external components. Engineered to meet IEC 60947-6-1 standards, it ensures compliance in demanding industrial and commercial environments.

 

Constructed with a steel-sheet enclosure offering IP54 protection against dust and water ingress, the system accommodates harsh operational conditions while maintaining safety. It supports four poles with simultaneous switching functionality, positioned on the left and right sides of the unit. The ATS employs bolt-type terminals for secure electrical connections at input/output positions located at the bottom of the enclosure.

 

Operational ratings include a continuous current capacity of up to 630 A under fully enclosed conditions at 40 °C ambient temperature. It handles rated voltages ranging from 200 V AC to 480 V AC across various duty classifications (AC-31B, AC-32B, AC-33B). With an impulse withstand voltage rated at 12 kV and insulation voltage rated at up to 1000 V, it delivers dependable connectivity under fluctuating load scenarios. Additionally, this device achieves a short-time withstand current rating (Icw) of 30 kA for durations up to 0.3 seconds—ensuring resilience during transient fault events.

 

Positioned as a delayed-transition ATS with bottom cable entry points optimized for installation flexibility, its pollution degree classification is set at level three per industry specifications. Compactly built with dimensions of 610 mm width x 810 mm height x 300 mm depth and weighing approximately 80 kg net (gross weight: ~85 kg), this product supports transport efficiency while meeting large-scale equipment demands within its WEEE category classification (Category #4).

 

Designed for industrial automation systems or infrastructure requiring smooth transition technology in applications such as marine operations or power generation facilities—this solution offers reliable energy distribution tailored to complex B2B requirements across multiple sectors globally.
