Mersen A60C150-121 - Mersen low-voltage capacitor fuses provide advanced safety for power correction and harmonic filtering equipment. A capacitor fuse isolates a shorted capacitor before it can damage surrounding equipment or personnel. Typical capacitor failures occur when the internal dielectric can no longer withstand the applied voltage, resulting in a low impedance current path and generating excessive heat and pressure that can cause violent case rupture. Mersen A60C fuses will isolate the shorted capacitor before case rupture occurs while routinely withstanding inrush current at startup.
