The ABB OT400ES03 is a heavy-duty 400 A, 3-pole side-operated switch-disconnector designed for dependable switching and isolation in low-voltage industrial electrical systems. Part of the established ABB OT switch-disconnector range, it provides reliable manual isolation for power distribution, machinery, switchboards and electrical control applications.
The OT400ES03 uses a side-operated, base-mounted configuration, making it suitable for switchboard and panel arrangements where side operation is preferred. The switch is supplied without an operating handle and shaft, allowing the appropriate ABB operating accessories to be selected separately according to the enclosure and installation requirements.
With a rated current of 400 A and a 3-pole configuration, the OT400ES03 is designed for demanding three-phase isolation duties. It provides 400 A AC-22A and AC-23A performance at 400–415 V AC, while its main circuit is rated for operation up to 1000 V.
Switch-disconnectors such as the ABB OT400ES03 provide a dependable means of manually switching and isolating electrical circuits. This enables downstream machinery and electrical equipment to be disconnected from the power supply for maintenance, servicing and operational control.
The OT400ES03 combines a 400 A current rating with a 3-pole, side-operated configuration. Its base-mounted construction and separately selected handle and shaft provide installation flexibility for industrial switchboards, machinery and electrical control panels where side operation is required.
