Why Choose the ABB OT250E03YP Manual Bypass Switch?
The ABB OT250E03YP is a 250 A 3-pole manual bypass switch designed to provide a controlled bypass path in industrial electrical systems. Supplied under ABB product ID 1SCA123553R1001 and forming part of the ABB OT Change-over Switches range, it combines high-current manual switching with a purpose-designed bypass configuration.
The OT250E03YP uses an open-transition I-O-II switching arrangement and 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 can be removed when the standard handle needs to be padlocked.
With a rated current of 250 A and a 3-pole configuration, the OT250E03YP is suitable for demanding three-phase bypass applications. It provides AC-21A/AC-22A switching at 250 A, a rated apparent power of 170 kVA at 400 V, and an AC-23A rating of 250 A / 140 kW at 400–415 V.

Reliable Three-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 to be isolated for inspection, servicing or maintenance while the electrical system is operated through the designated bypass path.
The ABB OT250E03YP combines this bypass functionality with three-pole construction, a 250 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 practical package for integration into industrial switchboards and control assemblies.
Typical Applications
- Manual equipment bypass systems.
- Variable frequency drive bypass arrangements.
- Three-phase industrial motor and drive installations.
- Maintenance and service bypass circuits.
- Industrial electrical distribution switchboards.
- OEM control panels and power distribution assemblies.
