A6K70R - 70Amp Fuse

A6K70R - 70Amp Fuse

The Mersen A6K70R Amp-Trap® Class RK1 Fast-Acting Fuse is built for your electrical systems that need dependable protection from overloads and short circuits. Rated at 70 Amps, this fuse is commonly used in commercial and industrial applications where keeping equipment protected and minimizing downtime are part of everyday operation.

When fault conditions occur, the A6K70R is designed to react quickly, helping reduce the amount of fault current moving through the circuit. That fast response can help protect your transformers, control panels, disconnects, HVAC systems, and other electrical equipment commonly used in power distribution systems and industrial facilities.

Part of Mersen’s trusted Amp-Trap® A6K-R series, this Class RK1 fast-acting fuse is designed for systems with high available fault currents. The blade-style terminals provide secure clip mounting, while the PolyTube body is made for dependable performance in demanding electrical environments.

With a high 200 kA interrupting rating, the A6K70R is often used in manufacturing facilities, commercial buildings, industrial machinery, and electrical distribution equipment where reliable overcurrent protection is important.
