Overview

The Mersen A150C50-20 is a critical component for medium voltage capacitor protection, designed to meet ANSI C37-41 standards. This Amp-Trap® series fuse operates silently without noise or discharge, suitable for indoor or outdoor use within a weatherproof enclosure. It provides essential short circuit and overload protection, safeguarding capacitor banks against dielectric failure and case rupture. Engineered for reliability, this non-disconnecting fuse requires a disconnect switch for operation. Key specifications include a 1500 VAC voltage rating and a 50 A current rating. The A150C50-20 features a male stud to L bracket connection, facilitating direct mounting. Its interrupting rating is 40 kA Sym at 1500V RMS. The overall length is 8.11 inches (206.0 mm), with a tube length of 5.74 inches (145.8 mm). The body diameter is 0.75 inches (19.1 mm), and the bracket dimensions are 1.10 inches (27.9 mm) by 7.49 inches (190.2 mm). Manufactured in the US, this fuse offers a cost-effective and space-saving solution for protecting power correction and harmonic filtering equipment. Ensure proper application with a disconnect switch for safe and effective operation.
