Why Choose the ABB OT400E22YP 400 A 4-Pole Bypass Changeover Switch?
The ABB OT400E22YP is a heavy-duty 400 A 4-pole manual bypass changeover switch designed for reliable load bypass and source-routing duties in low-voltage power distribution systems. Part of the ABB OT Changeover Switches range, it provides a practical solution for installations where equipment must be isolated for maintenance while the load continues to receive power through a bypass path.
This model uses an I-O-II open-transition operating sequence, providing a defined OFF position between its operating states. Its 4-pole configuration enables four conductors to be switched together, making it suitable for substantial four-pole electrical distribution and bypass arrangements.
Rated at 400 A, the OT400E22YP provides 400 A AC-21 and AC-23 switching capability at 400 V, with an AC-23 operational power rating of 220 kW at 400 V. It is supplied with a shaft and black IP65 operating handle, providing the principal components required for manual panel operation.

Reliable Load Bypass for Maintenance and Power Distribution
Bypass switches are used where electrical equipment must be taken out of the normal power path while continuity of supply to the load is maintained through an alternative bypass route. The ABB OT400E22YP provides a manually operated four-pole arrangement for implementing this function in suitably designed low-voltage distribution systems.
The OT400E22YP combines a 400 A rating with I-O-II open-transition operation and robust AC-23 switching performance. This makes it particularly suitable for maintenance bypass arrangements where connected equipment can be isolated while the load is supplied directly from the appropriate source.
Typical Applications
- UPS maintenance bypass systems.
- Industrial load bypass arrangements.
- Equipment maintenance and isolation systems.
- Industrial low-voltage distribution switchboards.
- Four-pole electrical distribution systems.
- Commercial and infrastructure power installations.
