OXB800E3S3Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB800E3S3Q54B is an enclosed automatic transfer switch specifically designed to ensure reliable, uninterrupted power delivery in critical applications. Built in compliance with IEC 60947-6-1 standards, this robust ATS integrates the switching mechanism and controller in a single unit for enhanced operational efficiency. Rated for use in systems within a voltage range of 200–480 V AC and capable of handling currents up to 700 A (AC-31B/32B/33B), it offers adaptability across diverse industrial environments.

 

The assembly features steel sheet construction with an IP54 protection rating per IEC 60529, ensuring resistance against dust ingress and limited water exposure—suitable for challenging installation conditions. Equipped with a direct-mounted handle and bottom cable entry design, it simplifies integration into existing setups while enabling streamlined access to line terminals positioned at the bottom (input/output). The fourth pole type operates via simultaneous switching functionality, located on both left and right sides.

 

Electrical performance includes a rated impulse withstand voltage (Uimp) of 12 kV, insulation voltage (Ui) rated at 1000 V, as well as short-time withstand current capabilities reaching up to 30 kA for durations of up to 0.3 seconds—making it particularly suitable for high-demand applications requiring system robustness under fault conditions. Additional technical specifications include thermal current ratings: Ith = 800 A free-air operation at Θ =40 °C; Ithe = fully enclosed configuration supporting continuous performance at up to 700 A.

 

Engineers will appreciate its Level-3 LCD controller interface offering advanced monitoring controls while distributors can leverage assured material conformance documented through RoHS Directive compliance alongside REACH declarations. This solution exemplifies durability paired with precise functionality tailored for mission-critical power management requirements in industries such as oil & gas, marine operations, or infrastructure facilities reliant on dependable energy transitions during contingencies.
