Overview

The Mersen A150C125-10 Medium Voltage Capacitor Fuse is a high-performance Amp-Trap® fuse designed to ANSI C37-41 standards for capacitor protection. Rated at 1500V AC and 125A, this fuse provides both short-circuit and overload protection to prevent capacitor case rupture or dielectric failure. It features a visual blown-fuse indicator for quick status verification and is suitable for indoor or outdoor use in weatherproof enclosures. The non-venting design ensures silent operation without discharge noise. With a phase interrupting rating of 40 kA RMS symmetric, it meets the demands of medium voltage capacitor banks in power correction and harmonic filtering systems. Available in multiple mounting configurations (external female-to-female, screw-to-bolt, clip style, or bus mount), it offers flexible installation options for OEMs and end-users. 248.1, ensuring compliance with safety standards. Designed for reliability, it withstands capacitor inrush currents while isolating faults before catastrophic failure occurs.
