Why Choose the ABB OT200KLAA4C Enclosed Change-Over Switch?
The ABB OT200KLAA4C is a heavy-duty 200 A 4-pole steel enclosed change-over switch designed for dependable manual transfer between two electrical supplies in low-voltage industrial and commercial installations. As part of the ABB OT change-over switch range and ABB product group 311019-Metal Enclosed (Loadbreak), it combines robust switching performance with a durable steel sheet enclosure.
Designed for front-operated source change-over applications, the OT200KLAA4C features a black pistol-type operating handle with I-O-II indication. This provides clear selection between source I, the centre OFF position and source II, making the switch suitable for applications such as mains-to-generator transfer, alternative supply selection and other manually controlled source-transfer systems.
With a rated operational current of 200 A and a 4-pole configuration, the OT200KLAA4C allows four conductors to be transferred together. The steel sheet enclosure is supplied with open top and bottom cable-entry sides, allowing C-flanges or ring-flanges to be selected separately to suit the installation.
Key Advantages
- Heavy-duty 200 A enclosed change-over switch.
- 4-pole configuration for simultaneous transfer of four conductors.
- I-O-II switching provides two supply positions with a defined centre OFF position.
- Durable steel sheet enclosure for industrial installations.
- Open top and bottom cable entries provide installation flexibility.
- Compatible with separately ordered C-flanges or ring-flanges.
- Black pistol-type operating handle provides clear source-position indication.
- Suitable for mains-generator, alternative supply and manual source-transfer applications.

Reliable Manual Source Change-Over and Isolation
Change-over switches provide a controlled means of selecting between two electrical supplies while preventing both normal operating positions from being selected simultaneously. The centre OFF position provides electrical isolation between source I and source II, making manually operated change-over switches useful in standby power, generator and alternative supply systems.
The OT200KLAA4C combines a 200 A rating with 4-pole I-O-II switching and a steel sheet enclosure. Its four-pole arrangement enables four conductors to be transferred together, while the open-entry enclosure allows suitable C-flange or ring-flange cable-entry components to be selected according to the cabling requirements of the installation.
Typical Applications
- Mains-to-generator manual change-over systems.
- Alternative electrical supply selection.
- Standby power distribution systems.
- Industrial machinery supply transfer.
- Commercial and industrial building services.
- Low-voltage power distribution installations.
- Four-pole manual source-transfer applications.
