UL-Rated High-Current Isolation for Industrial Power Systems

Non-fusible disconnect switches provide a dedicated means of manually switching and isolating electrical circuits without incorporating overcurrent protection into the switching device itself. The ABB OT1200U12P combines a 1200 A UL/CSA rating with three-pole switching, making it suitable for high-current three-phase distribution systems where circuit protection is provided separately.

The OT1200U12P is designed specifically for demanding UL/CSA and IEC installations. Its UL 98 approval, 600 V UL/CSA maximum operating voltage, substantial short-circuit withstand performance and supplied handle and shaft provide a robust solution for industrial switchboards, machinery and high-power distribution equipment.

Typical Applications

• UL/CSA industrial power distribution systems.
• High-current three-phase electrical isolation.
• Industrial switchboards and distribution assemblies.
• Large machinery and production equipment.
• Main and sub-main disconnect applications.
• Manufacturing and process facilities.
• High-power feeder and equipment isolation.
