Why Choose the ABB OT400E13C Manual Change-Over Switch?
The ABB OT400E13C is a heavy-duty 400 A 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 dependable I-O-II switching for industrial, commercial and infrastructure power distribution applications.
The OT400E13C uses an I-O-II open-transition operating sequence, providing a defined OFF position between source I and source II. This break-before-make arrangement disconnects one source before the alternative source is connected, supporting controlled manual transfer and electrical isolation.
With a rated current of 400 A, the OT400E13C features the E13 modular mechanism configuration and front operation. This version is supplied without the operating handle and shaft, allowing suitable ABB operating accessories to be selected separately to suit the switchboard or enclosure installation.

Reliable Manual Power Source Change-Over
Manual change-over switches provide a controlled method of selecting between two electrical supplies. The ABB OT400E13C uses an I-O-II open-transition arrangement so that the active source is disconnected before the alternative source is connected, with a defined OFF position available between source selections.
The OT400E13C is engineered for demanding low-voltage distribution systems. Its 400 A current rating, 220 kW AC-23 rating at 400 V and 15 kA short-time withstand capability make it suitable for industrial switchboards, generator change-over arrangements and other high-current manual source-transfer applications.
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 manual source-transfer systems.
- Manufacturing plants and industrial power installations.
