Why Choose the ABB OT630E12CP Manual Change-Over Switch?
The ABB OT630E12CP is a heavy-duty 630 A 3-pole manual change-over switch designed for dependable transfer between two electrical power sources in low-voltage distribution systems. As part of the ABB OT change-over switch range, it provides robust manual source selection for industrial, commercial and infrastructure electrical installations.
The OT630E12CP uses an I-O-II open-transition operating arrangement, providing two source positions with a defined OFF position between them. Its operating mechanism is positioned between the poles, providing an alternative physical arrangement for switchboard designs where the mechanism position is important.
Rated at 630 A with a 3-pole configuration, the OT630E12CP is designed for demanding three-phase power distribution applications. It includes a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connection, while the handle is padlockable in the O position for secure isolation.

Reliable Manual Power Source Change-Over
Manual change-over switches provide a controlled means of selecting between two electrical supplies. The ABB OT630E12CP combines I-O-II open-transition operation with a mechanism positioned between the poles, allowing the active supply to be disconnected before the alternative supply is selected while providing a defined OFF position.
The OT630E12CP is engineered for demanding low-voltage distribution applications. Its 630 A current rating, 355 kW AC-23A rating at 400 V and 20 kA short-time withstand capability make it suitable for industrial switchboards, generator change-over arrangements and other high-current three-phase source-transfer systems.
Typical Applications
- Mains and alternative power source selection.
- Generator and mains manual change-over systems.
- Industrial low-voltage distribution switchboards.
- Commercial and infrastructure electrical distribution.
- High-current three-phase source-transfer systems.
- Manufacturing plants and industrial power installations.
