Why Choose the ABB OT400E04YP Manual Bypass Switch?
The ABB OT400E04YP is a heavy-duty 400 A 4-pole manual bypass switch designed to provide controlled bypass switching in industrial electrical systems. Supplied under ABB product ID 1SCA124026R1001 and forming part of the ABB OT Change-over Switches range, it provides a purpose-designed solution for applications where connected equipment may need to be bypassed for servicing, maintenance or operational requirements.
The OT400E04YP uses an open-transition I-O-II switching arrangement and features its operating mechanism at the left-hand end of the switch. It is supplied with a black plastic IP65 I-O-II pistol handle, a snap-on handle extension for smooth manual operation, an operating shaft and a bolt set for cable connection. The handle extension is removed when the standard handle needs to be padlocked.
With a rated current of 400 A and a 4-pole configuration, the OT400E04YP is suited to demanding bypass applications requiring four switched conductors. It provides AC-21A/AC-22A switching at 400 A, a rated apparent power of 275 kVA at 400 V, and an AC-23A rating of 400 A / 220 kW at 400–415 V.

Reliable Four-pole Manual Bypass Switching
A manual bypass switch provides an alternative electrical path around connected equipment. In a correctly engineered installation, this allows compatible equipment such as a variable frequency drive to be isolated for inspection, servicing or maintenance while the load is supplied through the designated bypass path.
The ABB OT400E04YP combines this bypass functionality with four-pole construction, a 400 A current rating and open-transition I-O-II manual operation. Its supplied IP65 pistol handle, removable handle extension, operating shaft and connection hardware provide a comprehensive operating package for integration into industrial switchboards, motor-control systems and drive installations.
Typical Applications
- Manual equipment bypass systems.
- Variable frequency drive bypass arrangements.
- Four-pole industrial motor and drive installations.
- Maintenance and service bypass circuits.
- Industrial electrical distribution switchboards.
- OEM control panels and power distribution assemblies.
