1SCA022839R9690 ABB 250A 3-Pole IP65 ATEX Enclosed Safety Switch

Why Choose the ABB OT250KLRR3TX 250A 3-Pole ATEX Enclosed Safety Switch?

The ABB OT250KLRR3TX is a heavy-duty 250 A three-pole ATEX enclosed safety switch-disconnector designed for dependable load switching and electrical isolation in industrial locations where ATEX-rated equipment is required. Part of the ABB OT enclosed switch range, it combines high-current switching with a robust steel enclosure and hazardous-area construction.

Designed for local safety isolation, the OT250KLRR3TX uses a black I-O / ON-OFF operating handle and provides IP65 enclosure protection. The ATEX configuration is intended for Ex II 3D applications, while the enclosed design provides a practical isolation point for machinery, motors and electrical equipment installed in applicable dust-hazard environments.

The OT250KLRR3TX is rated at 250 A across AC-23A duties at 400 V, 500 V and 690 V. Cable entry is provided at the top and bottom through four ring-flange positions per side, while the enclosure measures approximately 600 × 400 × 230 mm and weighs approximately 21 kg.
