OXB1000E3S3Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB1000E3S3Q54B is an enclosed automatic transfer switch (ATS), purpose-engineered to integrate both a switch and controller within a single unit, ensuring robust and seamless performance for critical power applications. Designed in compliance with IEC 60947-6-1 standards, this device supports steady operational resilience in demanding environments.

 

With dimensions of 810 mm width, 1010 mm height, and 300 mm depth, the enclosure is constructed from durable steel sheet and offers IP54 protection against dust and water ingress as per IEC 60529 standards. Key electrical specifications include a rated insulation voltage (Ui) of 1000 V, impulse withstand voltage (Uimp) of 12 kV, conventional free-air thermal current of up to 1000 A at Θ = 40 °C, and operational voltage ranges between 200–480 V AC. The ATS accommodates AC-31B/AC-32B/AC-33B application loads up to its maximum current rating of 1000 A at voltages between 200–415 V AC. Additionally, it features delayed transition type functionality for stability during transfer operations.

 

This system incorporates bottom cable entry terminals designed with bolt-type connections for secure terminations. It is equipped with Level 3 LCD-based control technology which ensures precise monitoring and operation flexibility. The fourth pole allows simultaneous switching functions on the left or right side based on application needs. Furthermore, rigorous performance testing certifies its ability to withstand short-time currents up to 50 kA rms for durations of up to 0.3 seconds.

 

Meeting environmental directives such as RoHS (EU Directive 2011/65/EU + Amendment) and REACH regulations ensures adherence to international material compliance norms while aligning with sustainable practices under WEEE category "4: Large Equipment." Weighing approximately net weight of115 kg., this product delivers unwavering reliability required by mission-critical industrial systems ranging from oil & gas facilities , power generati
