OT125FPC-B ABB 125 A 4-Pole IP65 Steel Enclosed Manual Changeover Switch

Why Choose the ABB OT125FPC-B Manual Changeover Switch?

The ABB OT125FPC-B is a robust 125 A manual changeover switch designed for dependable switching between two electrical supplies in industrial and commercial low-voltage installations. As part of ABB's metal-enclosed load-break switch range, it combines manual changeover functionality with a durable steel enclosure for power distribution and supply-transfer applications.

Designed for installations requiring a manually controlled changeover point, the OT125FPC-B enables an electrical load to be transferred between alternative supplies without relying on an automatic transfer mechanism. Its enclosed construction protects the switching equipment and provides a practical, self-contained solution for switchboards, building services, machinery and standby-power systems.

With a rated current of 125 A, a 4-pole configuration and an IP65 steel enclosure, the OT125FPC-B is particularly suitable for three-phase and neutral systems requiring robust manual source selection. The four-pole arrangement enables all four conductors to be switched as part of the changeover operation.

Reliable Manual Supply Changeover

Manual changeover switches provide a controlled means of transferring an electrical load between two separate power sources. The ABB OT125FPC-B combines this functionality with a 125 A current rating and 4-pole switching, making it suitable for three-phase systems where the neutral conductor also forms part of the changeover arrangement.

The IP65 steel enclosure provides protection against dust and water ingress, allowing the switching equipment to be installed in demanding electrical environments. Manual operation makes the OT125FPC-B suitable for installations where operators need a straightforward and dependable means of selecting between normal and alternative power supplies.

Typical Applications

• Manual mains-to-generator changeover systems.
• Normal and standby power-source selection.
• Industrial low-voltage power distribution.
• Three-phase and neutral supply-transfer systems.
• Commercial building-services installations.
• Manufacturing and process plant electrical systems.
• Machinery and equipment requiring alternative power supplies.
