Why Choose the ABB OT800E03YP 800 A 3-Pole Manual Bypass Switch?
The ABB OT800E03YP is a heavy-duty 800 A 3-pole manual bypass switch designed for dependable load bypass in high-current low-voltage power distribution systems. Part of the ABB OT Changeover Switches range, it provides a practical means of isolating equipment for maintenance while allowing the load to be supplied directly through a bypass path.
The OT800E03YP uses an I-O-II open-transition switching arrangement, providing a defined OFF position as part of the manual operating sequence. Its 3-pole configuration is suited to three-phase electrical systems where the three phase conductors require coordinated bypass switching.
Rated at 800 A, the OT800E03YP provides 800 A AC-21A/AC-22A capability at up to 415 V and 800 A / 450 kW AC-23A capability at 400–415 V. It is supplied with a black plastic IP65 I-O-II pistol handle, handle extension, operating shaft and cable connection bolt set for convenient manual operation and switchboard integration.

Reliable High-Current Load Bypass for Maintenance
Manual bypass switches provide a controlled method of removing equipment from the normal power path while maintaining a direct route between the appropriate source and load. The ABB OT800E03YP combines this bypass functionality with an I-O-II open-transition arrangement, allowing deliberate manual selection and a defined OFF position.
With its 800 A rating, three-pole construction and 450 kW AC-23A capability at 400–415 V, the OT800E03YP is designed for substantial three-phase installations. The supplied handle extension helps provide smooth manual operation, while the shaft, handle and connection hardware support practical integration into suitably designed electrical assemblies.
Typical Applications
- UPS maintenance bypass systems.
- Industrial load bypass arrangements.
- Equipment maintenance and isolation systems.
- High-current low-voltage distribution switchboards.
- Three-phase industrial power distribution systems.
- Commercial and infrastructure power installations.
