OT250E03K ABB 250 A 3-Pole Switch-Disconnector with Direct-Mounted Handle

Why Choose the ABB OT250E03K Switch-Disconnector?

The ABB OT250E03K is a robust 250 A three-pole switch-disconnector designed for reliable switching and electrical isolation in industrial power distribution, machinery and control-panel applications. As part of the established ABB OT switch-disconnector series, it provides dependable manual isolation in a compact base-mounted format.

This model is front operated with a direct-mounted handle, providing convenient local operation without requiring a separate external handle arrangement. ABB supplies the OT250E03K with a black Test-OFF-ON plastic direct-mount handle and shaft as standard, with the handle padlockable in the OFF position for secure isolation.

With an open-air thermal current rating of 250 A, the OT250E03K provides rated operational currents of 250 A AC-22A and 250 A AC-23A at 400–415 V. The combination of three-pole switching, direct operation and included installation hardware makes it well suited to industrial panels and switchboards requiring straightforward, dependable isolation.

Direct-Mounted Switching and Secure Isolation

A direct-mounted handle provides local manual control directly at the switch-disconnector, making this configuration particularly useful where the switching device itself is accessible within the equipment design. The Test-OFF-ON indication gives operators a clear representation of the switch position during normal operation and maintenance.

The OT250E03K combines 250 A three-pole switching with a factory-supplied direct-mount handle and shaft. The ability to padlock the handle in the OFF position supports controlled isolation procedures, while the included terminal bolt kit simplifies integration into industrial electrical assemblies.

Typical Applications

• Industrial three-phase power distribution.
• Machine and equipment isolation.
• Electrical control panels and cabinets.
• Industrial switchboards and distribution assemblies.
• Manufacturing and process equipment.
• OEM machinery requiring direct local isolation.
