PSX Powr-Speed® High-Speed Square Body Fuses

Littelfuse PSX Powr-Speed® High-Speed Square Body Fuses are extremely fast-acting, offering high-speed performance up to 1500VDC, ranging from 80A to 1400A in small NH XL package sizes. The PSX series is available with multiple mounting terminations, including bolted-blade, DIN-blade, and metric flush-end styles. Visual blown fuse indication is standard on all fuses, and an optional micro-switch is available for external indication. These fuses are certified to UL248-13 and designed to meet EN high-speed semiconductor fuse standards and future battery protection fuse standards. Littelfuse PSX Powr-Speed High-Speed Square Body Fuses are specially designed to protect battery energy storage systems (BESS) and photovoltaic inverters. These fuses are also ideal for DC applications such as DC common bus systems, larger industrial regenerative drives, rectifiers, and metal processing equipment.
