OT400E03DP ABB 400A 6-Pole Switch-Disconnector

Why Choose the ABB OT400E03DP 400A 6-Pole Switch-Disconnector?

The ABB OT400E03DP is a heavy-duty 400 A six-pole switch-disconnector designed for reliable multi-pole load switching and electrical isolation in industrial low-voltage systems. Part of the ABB OT switch-disconnector range, it provides simultaneous operation of six poles for applications requiring more conductors to be isolated than with conventional three- or four-pole switching devices.

The OT400E03DP is a front-operated, base-mounted IEC switch-disconnector. Its six-pole arrangement is constructed so that the switching sections operate together from a single operating mechanism, providing coordinated ON-OFF switching across all six poles.

Rated at 400 A open-air thermal current, the OT400E03DP provides 400 A AC-22A and 400 A AC-23A operational current at 400–415 V AC. It is supplied as standard with a black ON-OFF plastic pistol handle, extension and adjustable shaft, with the installed handle providing IP65 protection and padlocking in the OFF position.

Coordinated Six-Pole Switching and Electrical Isolation

Six-pole switch-disconnectors provide simultaneous switching and isolation of multiple conductors from a common operating mechanism. In the ABB OT400E03DP, the switching sections are mechanically coordinated so that all six poles operate together when the handle is moved between its O and I positions, providing straightforward multi-pole isolation from one control point.

The OT400E03DP combines a 400 A rating, six-pole configuration and 400 A AC-23A capability at 400–415 V AC with ABB's front-operated base-mounted construction. The included adjustable shaft and IP65-capable padlockable handle make it particularly suitable for enclosure-mounted industrial isolation duties.

Typical Applications

• Industrial six-pole electrical isolation.
• Multi-circuit and multi-conductor switching systems.
• Industrial switchboards and distribution panels.
• Machinery and process-equipment isolation.
• Manufacturing and production facilities.
• Applications requiring simultaneous operation of six switching poles.
