Product Description
The A6K40R fuse is a 40 Amp, 600 Volt AC / 300 V DC fast‑acting, current‑limiting cartridge fuse designed for branch circuits, feeder circuits, panelboards, and industrial electrical systems. As part of the Amp‑Trap® A6K‑R series, the A6K40R delivers reliable overload and short‑circuit protection where high available fault currents exist. Its rejection‑style design helps prevent installation of incorrect fuse classes, making it a reliable choice for maintenance, repairs, or equipment builds.
