The GOULD SHAWMUT A50P150 (Mersen/Ferraz Shawmut) is an Amp-Trap® Form 101 high-speed (fast-acting) semiconductor fuse for protecting rectifiers, inverters, and DC common-bus rails in UPS and power-electronic systems. This listing features reclaimed, continuity-tested units removed from decommissioned, fully functional equipment.
High-Speed Protection:
Very fast-acting, current-limiting element with low I²t for semiconductor safety.
Bolt-Down Blade Body:
Round Form 101 cartridge with tin-plated bolt-in blades for robust, low-impedance connections.
500 VAC / 450 VDC Class:
Suitable for higher-voltage AC/DC drives, UPS systems, and inverter stacks.
Reclaimed & Verified:
Every unit is continuity-tested and visually inspected; new Mersen stock available by request.
