A6D75R - 75 Amp Fuse

A6D75R - 75 Amp Fuse

Electrical systems don’t always run under perfect conditions, especially when motors and heavy equipment are starting up throughout the day. The A6D75R Class RK1 Time-Delay Fuse is designed to handle those temporary startup surges while still providing dependable protection when real fault conditions happen. Rated at 75 Amps, this fuse helps protect your motors, feeders, branch circuits, and other electrical equipment from overloads and short circuits without unnecessary interruptions.

This fuse also features a current-limiting design that helps reduce the amount of energy released during short-circuit events. That added protection can help you minimize stress on electrical components and improve overall system reliability. With a high 200 kA interrupting rating at 600VAC, the A6D75R is well-suited for systems with high available fault currents often found in manufacturing facilities, HVAC systems, motor control centers, and heavy-duty commercial equipment.

The knife-blade style construction provides secure installation in compatible fuse holders, while the compact size allows it to fit a variety of industrial and commercial electrical applications.
