OXB630E3S4Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB630E3S4Q54B is an enclosed automatic transfer switch (ATS) designed to ensure uninterrupted power delivery for critical applications. With advanced integration, it combines a high-performance switch and Level 4 touch controller into a single compact unit, providing operational precision and reliability beyond industry standards. Engineered to comply with IEC 60947-6-1 safety requirements, the device supports various applications with its rated operational current of 630A across AC-31B, AC-32B, and AC-33B categories at voltages ranging from 200V to 415V AC. Its robust steel sheet enclosure offers IP54 protection against environmental factors in accordance with IEC 60529 standards.

 

Key electrical characteristics include a rated impulse withstand voltage of 12 kV, rated insulation voltage of up to 1000 V, and short-time withstand current capability of up to 30 kArms for low-voltage circuits over a duration of 0.3 seconds. Designed with flexibility in mind, it features bottom entry terminals configured as Bottom-In/Bottom-Out connections and delayed transition switching for optimized circuit management during power transfers.

 

The unit includes four poles (switched simultaneously) with handle positioning options for direct mounting alongside left or right-side fourth pole placement adaptability. Additional certifications encompass compliance with RoHS Directive EU2011/65/EU + Amendment EU2015/863 and CE Declaration standards.

 

Compact dimensions—810 mm height x 610 mm width x 300 mm depth—and weight specifications (80 kg net; packaged gross weight: ~85 kg) make installation streamlined across diverse industrial setups such as oil & gas facilities or building infrastructures requiring dependable ATS systems under pollution degree category "3."
