Why Choose the ABB OT1000E12CP Manual Change-Over Switch?
The ABB OT1000E12CP is a heavy-duty 1000 A three-pole manual change-over switch designed for reliable switching between two electrical power sources. Part of ABB's OT change-over switch range, it provides I-O-II open-transition operation for industrial power distribution, standby power and source-selection applications.
Rated at 1000 A, the OT1000E12CP is engineered for high-current installations where dependable manual source selection and isolation are required. Its three-pole configuration is suitable for three-phase systems, while the open-transition operating sequence ensures that one source is disconnected before the alternative source is connected.
The OT1000E12CP is supplied with a black plastic IP65 I-O-II pistol-type handle, operating shaft and terminal bolt set. The handle can be padlocked in the OFF position and provides door interlocking in the I and II positions, supporting controlled operation and secure electrical isolation.

Reliable Manual Source Change-Over for High-Current Power Systems
Manual change-over switches provide a mechanically controlled means of selecting between two electrical power sources while preventing unintended simultaneous connection. The ABB OT1000E12CP uses an open-transition I-O-II operating sequence, meaning the connected source is opened before the alternative source is connected.
With its 1000 A three-pole rating and high AC-23A switching capability, the OT1000E12CP is designed for substantial three-phase distribution systems. Its supplied door-mounted handle, shaft and terminal hardware provide a coordinated ABB solution for integration into switchboards and source-selection panels.
Typical Applications
- Manual mains and generator change-over systems.
- Industrial power-source selection.
- High-current electrical distribution switchboards.
- Standby and alternative power systems.
- Commercial and infrastructure power distribution.
- Industrial plants and manufacturing facilities.
- OEM change-over and power-control panels.
