Why Choose the ABB OT250ES04K 250A 4-Pole Side-Operated Switch-Disconnector?
The ABB OT250ES04K is a robust 250 A four-pole switch-disconnector designed for dependable load switching and electrical isolation in industrial low-voltage power systems. As part of the ABB OT switch-disconnector series, this model features a side-operated mechanism positioned on the left and a direct-mounted operating handle for convenient local operation.
The OT250ES04K combines a four-pole switching arrangement with side operation and base mounting, making it particularly useful where the layout of a switchboard or machine requires operation from the side of the device. The K-version includes a black ON-OFF direct-mount handle as standard, with the handle padlockable in the OFF position to support controlled electrical isolation.
With an open-air thermal current of 250 A and AC-22A/AC-23A operational ratings of 250/250 A at 400–415 V AC, the OT250ES04K is suitable for demanding industrial switching duties. Its compact construction, direct operating handle and included terminal bolt kit provide a practical solution for machinery, distribution boards and industrial control assemblies.

Reliable Side-Operated Isolation for Industrial Power Systems
Switch-disconnectors provide a defined means of manually switching loads and isolating electrical circuits from their power supply. A side-operated configuration can be particularly useful in switchboards and machinery where the equipment layout makes conventional front operation impractical or where direct local operation from the side is preferred.
The ABB OT250ES04K combines a 250 A current rating, four-pole construction and left-side operating mechanism with a direct-mounted handle. Its AC-23 switching capability and padlockable OFF position make it suitable for industrial main-switch, machinery-isolation and power-distribution applications.
Typical Applications
- Industrial machinery isolation and main-switch applications.
- Four-pole low-voltage distribution systems.
- Industrial switchboards and electrical panels.
- Installations requiring side-operated switching.
- Manufacturing and process equipment.
- OEM machinery and industrial control assemblies.
