Why Choose the ABB OT400E03YP Bypass Switch?
The ABB OT400E03YP is a heavy-duty 400 A 3-pole manual bypass switch designed for reliable bypass switching in low-voltage electrical distribution systems. As part of the ABB OT change-over switch range, it provides an I-O-II operating arrangement for industrial, commercial and infrastructure applications requiring controlled manual routing of power.
The OT400E03YP uses an open-transition switching arrangement, providing a defined OFF position between its operating positions. It is supplied with a black plastic IP65 I-O-II pistol-type handle and a snap-on handle extension designed to provide smooth manual operation, together with the operating shaft and bolt set for cable connections.
With a rated current of 400 A and a 3-pole configuration, the OT400E03YP is engineered for demanding three-phase bypass applications. The handle is padlockable in the O position, while the operating arrangement provides door interlocking in the I and II positions and when padlocked, supporting controlled operation and isolation in electrical switchboards.

Reliable Manual Bypass Switching for Power Distribution
Manual bypass switches provide a controlled means of routing electrical power through an alternative path in appropriately designed distribution systems. The ABB OT400E03YP combines I-O-II operation with an open-transition arrangement, making it suitable for applications where equipment or a normal circuit path must be manually bypassed while maintaining controlled switching.
The OT400E03YP is designed for demanding low-voltage installations. Its 400 A rating, three-pole construction and 220 kW AC-23A rating at 400–415 V make it suitable for high-current industrial switchboards, maintenance bypass arrangements and other three-phase power distribution applications.
Typical Applications
- Industrial electrical equipment bypass arrangements.
- Maintenance bypass circuits.
- Industrial low-voltage distribution switchboards.
- Commercial and infrastructure power distribution systems.
- Three-phase high-current bypass applications.
- Manufacturing plants and industrial electrical installations.
