Why Choose the ABB OT200E03WC 200 A 3-Pole Changeover Switch?
The ABB OT200E03WC is a robust 200 A 3-pole manual changeover switch designed for reliable source selection in low-voltage electrical distribution systems. As part of the ABB OT Changeover Switches range, it provides I-O-II switching for industrial switchboards, distribution panels and alternative power supply systems.
This model features increased phase-to-phase spacing and an open-transition I-O-II switching arrangement, providing a defined OFF position between the two source positions. The three-pole construction is suitable for three-phase circuits, while the operating mechanism is positioned at the left-hand end of the switch.
Rated at 200 A, the OT200E03WC supports demanding industrial switching duties and is rated for operation up to 1000 V. This version is supplied without an operating handle and shaft, allowing the appropriate operating accessories to be selected separately for the installation.

Reliable Source Selection with Wide Phase Spacing
Manual changeover switches provide a controlled method of transferring a circuit between two electrical supplies. The ABB OT200E03WC uses an I-O-II open-transition arrangement, so the switching sequence passes through a defined OFF position between the two connected sources.
The OT200E03WC combines a 200 A three-pole configuration with increased phase-to-phase spacing, making it suitable for demanding switchboard and power distribution applications. Its separately selected handle and shaft arrangement also gives panel builders flexibility when configuring the operating system for a particular enclosure.
Typical Applications
- Main and alternative power supply changeover systems.
- Industrial low-voltage distribution switchboards.
- Generator and mains source-selection systems.
- Three-phase electrical distribution panels.
- Industrial machinery and plant power systems.
- Commercial and infrastructure electrical installations.
