ABB OT80F4C 4-pólový 80A prepínač (rukoväť nie je súčasťou) 1SCA105418R1001

In industrial and commercial power distribution, switching between two separate power sources—such as mains and backup generator—requires a robust, reliable change-over switch. The ABB OT80F4C is a 4-pole, 80 A load transfer switch engineered for exactly that task, ensuring safe and efficient source changeover without interruption.

Who is it for

This switch is intended for panel builders, electricians, and facility managers who need a compact, front-operated change-over solution for low-voltage distribution boards. It suits applications where manual switching between two independent supplies is required, such as in backup power systems, industrial machinery, or commercial buildings.

Main features
