Overview

The Mersen A70QS500-4IL Amp-Trap® fuse is engineered for superior protection of dynamic solid-state equipment. Developed to meet new equipment requirements for 700V semiconductor fuses, this high-speed fuse offers significantly lower I²t values, enhancing equipment protection. Its design also provides longer operational life when subjected to cyclic loading and reduces watts loss for cooler system operation. With a robust 700VAC/VDC rating, the A70QS series provides design versatility for applications up to 700V. The A70QS500-4IL features a bolted blade mounting type and an integrated IL indicator for visual or remote indication of fuse status. Key specifications include a 700V AC/DC voltage rating, 500A current rating, 200kA IR AC interrupting rating, and 100kA IR DC interrupting rating. Its superior cycling ability ensures reliability in demanding applications. This fuse is an optimal choice for protecting motor drives, UPS systems, inverters, and similar 700V or less equipment. It is UL recognized (File E60314) and CSA certified (File LR 12636).
