OT2500E04K ABB 2500 A 4-Pole Switch Disconnector with Direct-Mounted Handle

Why Choose the ABB OT2500E04K Switch Disconnector?

The ABB OT2500E04K, order code 1SCA108363R1001, is a heavy-duty 2500 A 4-pole switch disconnector designed for dependable manual switching and electrical isolation in high-current low-voltage power distribution systems. Part of the established ABB OT switch-disconnector series, it is engineered for demanding industrial switchboards, distribution assemblies and main isolation applications.

The OT2500E04K is a front-operated, base-mounted IEC switch disconnector supplied with a black Test-OFF-ON direct-mounted handle and shaft. The direct-mounted operating arrangement provides convenient local control directly at the switch, while the handle can be padlocked in the OFF position to support secure isolation procedures.

With an open-air thermal current of 2500 A and an AC-22A rated operational current of 2500 A at 400–415 V AC, the OT2500E04K is designed for substantial power distribution duties. Its 1000 V rated operational voltage, 55 kA short-time withstand current for 1 s and robust four-pole construction make it suitable for demanding high-current electrical installations.
