Why Choose the ABB OT400E03CP Manual Change-Over Switch?
The ABB OT400E03CP is a heavy-duty 400 A 3-pole manual change-over switch designed for reliable 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 OT400E03CP uses an I-O-II open-transition switching sequence with a stable OFF position between the two source positions. This break-before-make arrangement disconnects one source before the alternative source is connected, providing controlled source transfer and electrical isolation.
With a rated current of 400 A and a 3-pole configuration, the OT400E03CP is designed for demanding three-phase power distribution applications. It is supplied with a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connection, providing a complete manual operating arrangement for switchboard integration.

Reliable Manual Power Source Change-Over
Manual change-over switches provide controlled selection between two electrical supplies. The ABB OT400E03CP uses an open-transition I-O-II sequence so that the active source is disconnected before the alternative source is connected, with a stable OFF position available for controlled isolation between source selections.
The OT400E03CP is engineered for demanding low-voltage power distribution. Its 400 A current rating, three-pole construction, 15 kA short-time withstand capability and 220 kW AC-23A rating at 400–415 V make it suitable for high-current switchboards and manual 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.
- Three-phase high-current source-transfer systems.
- Manufacturing plants and industrial power installations.
