OXB1000E3S4Q54B ENCLOSED AUTOMATIC TRANSFER SWITCH

The OXB1000E3S4Q54B is an enclosed automatic transfer switch specifically designed to ensure reliable delivery of critical power for industrial and commercial applications. This unit integrates both the switching mechanism and controller into a compact, seamless design, conforming to IEC 60947-6-1 standards. Featuring four poles with simultaneous switched functionality and delayed transition type, this switch supports rated operational currents up to 1000 A across AC-31B, AC-32B, and AC-33B categories at voltages ranging from 200–480 V AC.

 

Built with a robust steel sheet enclosure providing IP54 protection (per IEC 60529), it is suitable for environments with Pollution Degree 3 classification. The system operates with a bolt-type terminal layout accommodating bottom-in-bottom-out cable entries. Rated insulation voltage stands at 1000 V, while impulse withstand voltage reaches up to 12 kV.

 

Engineered for high performance under demanding conditions, the OXB1000E3S4Q54B achieves a short-time withstand current rating of up to 50 kA (for 0.3 s) and utilizes direct-mounted control handles for ease of operation. Compact in design yet durable in construction, it measures 810 mm wide × 1010 mm high × 300 mm deep with a net weight of approximately ~115 kg.

 

This advanced enclosed style automatic transfer switch also includes Level 4 touch-controller capabilities optimized for secure operation within large-scale installations such as power generation systems or sensitive industrial automation infrastructures. It complies fully with EU RoHS directive requirements while meeting global regulatory safety certifications including CE conformity declarations—making it ideal for procurement engineers seeking technically refined solutions in critical infrastructure projects.
