Why Choose the ABB OT250ES30K 250A 3-Pole Side-Operated Switch-Disconnector?
The ABB OT250ES30K is a robust 250 A three-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 range, this model combines high-current switching capability with a side-operated configuration for installations where direct side access is preferred.
The OT250ES30K features a side-operated mechanism with a direct-mounted operating handle, providing convenient local ON/OFF control without requiring a separate external shaft-and-handle arrangement. Its three-pole configuration is suited to three-phase electrical systems, while base mounting supports straightforward integration into industrial panels, switchboards and machinery.
Rated at 250 A, the OT250ES30K is suitable for AC-20A, AC-21A, AC-22A and AC-23A switching duties at its specified current rating. The switch is designed to IEC 60947-3 and is supplied as standard with a direct-mounted handle, providing a practical high-performance isolation solution for industrial equipment and power distribution.

Reliable Side-Operated Switching and Isolation
Switch-disconnectors provide a defined means of manually switching electrical loads and establishing circuit isolation for operation, servicing and maintenance. Side-operated versions are particularly useful where switchboard or machine layouts favour access from the side rather than conventional front-mounted operation.
The ABB OT250ES30K combines a 250 A current rating, three-pole construction and direct side operation in a compact industrial design. Its direct-mounted handle eliminates the need for a separate remote operating arrangement, while its AC-23A capability supports demanding load-switching applications in three-phase industrial power systems.
Typical Applications
- Industrial machinery isolation and main-switch applications.
- Three-phase low-voltage power distribution systems.
- Industrial switchboards and electrical panels.
- Installations requiring direct side-operated switching.
- Manufacturing and process machinery.
- OEM equipment and industrial control assemblies.
