A6K45R - 45Amp Fuse

A6K45R - 45Amp Fuse

The Mersen A6K45R Amp-Trap® Class RK1 Fast-Acting Fuse is built to help protect your electrical systems when overloads or short circuits happen unexpectedly. Rated at 45 Amps, this fuse is commonly used in commercial and industrial equipment where dependable overcurrent protection is important for keeping your operations running safely.

The A6K45R is designed to react quickly during fault conditions, helping reduce the amount of fault current moving through the circuit. That fast response can help protect transformers, disconnects, control panels, HVAC equipment, and other electrical components from unnecessary damage.

Part of the Amp-Trap® A6K-R series, this Class RK1 fuse is made for applications where high available fault currents are present. The ferrule-style terminals provide secure clip mounting, while the PolyTube body is designed for dependable performance in demanding electrical environments.

With a high 200 kA interrupting rating, the A6K45R works well in manufacturing facilities, commercial buildings, industrial machinery, and power distribution systems where reliable fault protection is needed.
