OXB200E3S3Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB200E3S3Q54B is an enclosed automatic transfer switch (ATS) engineered for reliable power management in critical applications. It integrates both the switching mechanism and controller into a compact unit, complying with IEC 60947-6-1 standards. This model supports a rated operational voltage of 200–480 V AC across main circuits and operates at conventional thermal currents of up to 200 A. Designed with four poles, including simultaneous functionality for the fourth pole, it features bottom-entry line terminals and bolt-type connections for streamlined installation.

 

The enclosure is constructed from durable steel sheet material, offering protection classified as IP54 according to IEC 60529 standards. Its robust design ensures operation under harsh conditions with a pollution degree rating of 3. Equipped with delayed transition switching capabilities and an LCD Level 3 controller, this ATS provides advanced control options tailored for demanding industrial environments.

 

Technical highlights include a rated impulse withstand voltage (Uimp) of 8 kV, insulation voltage (Ui) up to 1000 V, and short-time withstand current (Icw) rated at 18 kA rms over 0.3 seconds. The dimensions—610 mm width, 810 mm height, and 300 mm depth—support effective integration into system designs while maintaining manageable weight parameters at approximately 52 kg net.

 

This solution addresses diverse power-intensive sectors such as industrial automation, oil & gas operations, marine systems, buildings infrastructure, and power generation facilities requiring consistent performance under stringent operational demands.
