Overview

The Mersen A430C90-70 is a medium voltage capacitor fuse designed for robust protection in electrical systems. Manufactured by Mersen, this Amp-Trap® series fuse operates at a maximum of 4300VAC with a 90A rating. It conforms to ANSI C37-41 standards, ensuring reliable performance. This non-disconnecting fuse requires a separate disconnect switch for operation and provides essential short circuit and overload protection. Its primary function is to safeguard capacitors against catastrophic failure, such as case rupture or dielectric breakdown. The A430C90-70 features a visual indicator for blown fuse status, simplifying maintenance and diagnostics. Designed for indoor general-purpose or outdoor weatherproof enclosures, it offers flexibility in installation. The female-to-female tube connection ensures secure mounting. With a high interrupting rating of 65 kA at 4300V RMS Sym, this fuse is built to handle significant fault currents. Its current-limiting operation is silent and produces no discharge, contributing to a safer operating environment. Mersen's commitment to quality and adherence to industry standards make this fuse a dependable choice for capacitor protection applications.
