OT Non-Fusible Disconnects

ABB OT Non-Fusible Disconnects are high-performance, compact disconnects with a current rating of up to 1.6kA and a voltage rating of up to 1.5kV_DC. The ABB OT Non-Fusible product line is designed to be virtually maintenance-free across the devices' lifetime. These durable disconnects are tested to IEC60947-3, UL508, UL98, and CSA. The modular design enables 2-, 3-, and 4-pole installation with different switching mechanism positions to suit a designer's needs and spatial requirements. The adjustable shaft (for external handles) and mounting feet, along with snap-on auxiliary contacts and terminal shrouds, save on installation time and costs.
