OXB800E3S4Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB800E3S4Q54B is an enclosed automatic transfer switch (ATS) engineered to meet IEC 60947-6-1 standards for reliable power continuity in critical applications. Integrating both switch and controller into one unit, this system delivers a compact design and streamlined functionality, performance-tested beyond standard requirements. It accommodates rated operational voltage from 200 V to 480 V AC across main circuits, with operational current ratings of up to 700 A for AC-31B, AC-32B, and AC-33B categories at voltages between 200–415 V AC.

 

Constructed with a steel sheet enclosure offering IP54 protection according to IEC 60529 and Pollution Degree rating of 3, the ATS is suitable for environments requiring robust sealing against dust and splashing liquids. Electrical specifications include a conventional free-air thermal current (Ith) of up to 800 A at Θ = 40 °C and a short-time withstand current (Icw) capability of up to 30 kA rms for durations of up to 0.3 seconds. With insulation performance rated at Ui =1000 V and impulse withstand voltage (Uimp) reaching up to 12 kV, it ensures secure operation under demanding electrical conditions.

 

Physical dimensions measure at a net width of 610 mm, height of 810 mm, depth/length of 300 mm, with terminals positioned “Bottom In”/“Bottom Out” for simplified cable entry management. The unit supports delayed transition types with switched simultaneous left/right fourth pole connections tailored for diverse application needs. Additional features include direct-mounted handle control paired with Level-4 Touch Controller technology ensuring precise configuration options.

 

This enclosed style ATS provides optimized energy transfer options across industrial sectors including buildings infrastructure automation systems requiring uninterrupted load switching during normal or emergency power events while adhering fully to RoHS directives as per EU Directive standards (2011/65/EU).
