A6K150R - 150Amp Fuse

A6K150R - 150Amp Fuse

The Mersen A6K150R Amp-Trap® Class RK1 Fast-Acting Fuse is a solid choice for protecting your electrical systems that can’t afford unnecessary downtime. Rated at 150 Amps, this fuse is designed to help you protect branch circuits, feeder circuits, and connected equipment from overloads and short-circuit conditions before serious damage occurs.

When a fault happens, every second counts. The A6K150R reacts quickly to help limit fault current and reduce stress on electrical components like transformers, disconnects, control panels, and switchgear. In busy commercial and industrial environments, that quick response can help you prevent larger system issues and reduce costly repairs.

This Class RK1 fuse is part of the trusted Amp-Trap® A6K-R series and is commonly used in applications where high available fault currents are present. Its blade-style terminals allow for secure clip mounting, and the PolyTube body is designed for dependable day-to-day performance in demanding electrical systems.

With a high 200 kA interrupting rating, the A6K150R is well suited for manufacturing equipment, HVAC systems, commercial buildings, industrial facilities, and power distribution applications where fast overcurrent protection is important.
