Why Choose the ABB OT250ES04 Switch-Disconnector?
The ABB OT250ES04 is a robust 250 A four-pole side-operated switch-disconnector designed for dependable switching and electrical isolation in industrial power distribution, machinery and switchboard applications. Part of the established ABB OT switch-disconnector series, it provides coordinated four-pole isolation for demanding low-voltage electrical systems.
This model features side operation with the operating mechanism positioned on the left, providing a practical alternative where enclosure layout or accessibility makes side operation preferable. The OT250ES04 is base mounted and supplied without a handle and shaft, allowing the appropriate ABB operating accessories to be selected separately for the installation.
With an open-air thermal current rating of 250 A, the OT250ES04 provides 250 A AC-22A and 250 A AC-23A operational current at 400–415 V. A terminal bolt kit is included as standard, making this four-pole switch-disconnector a flexible solution for industrial electrical assemblies requiring reliable high-current isolation.
Key Advantages
- Heavy-duty 250 A switch-disconnector for industrial switching and isolation.
- Four-pole configuration for simultaneous switching of four conductors.
- Side-operated design with mechanism on the left.
- Base-mounted construction for integration into switchboards and electrical enclosures.
- 250 A AC-22A and AC-23A performance at 400–415 V.
- Handle and shaft selected separately for installation flexibility.

Flexible Four-Pole Side-Operated Isolation
Side-operated switch-disconnectors are particularly useful where enclosure dimensions, busbar layouts or equipment accessibility favour operation from the side rather than the front. The OT250ES04 combines this installation flexibility with simultaneous four-pole switching, allowing four conductors to be disconnected together from a common operating mechanism.
The OT250ES04 is supplied without a handle and shaft, enabling suitable ABB operating accessories to be selected according to the enclosure depth and operating requirements. Its 250 A AC-22A and AC-23A ratings provide dependable switching capability for demanding industrial distribution and machinery applications.
Typical Applications
- Industrial four-pole power distribution.
- Three-phase systems requiring four-conductor isolation.
- Machine and equipment isolation.
- Side-operated electrical control panels.
- Industrial switchboards and distribution assemblies.
- OEM machinery and automation systems.
