Littelfuse PSX3XLFL1250 - POWR-SPEED SQB SIZE 3XL FLUSH 1250A. Littelfuse PSX series 1500 V dc high-speed square bodyfuses are specially designed to protect battery energy storage systems (BESS), photovoltaic inverters, and many of dc applications such as dc common bus systems, larger industrial regenerative drives, rectifiers and, metal processing equipment. The PSX series fuses are extremely fast-acting, offering high-speed performance up to 1500 V dc, ranging from 80 A to 1400 A in the smallest NH XL package sizes. The PSX series is available with multiple mounting terminations including flush-end style, DIN-style and bolted-blade style. Visual blown fuse indication is standard on all fuses and optional micro-switch is available for external indication. PSX series are certified to UL 248-13 and designed to meet EN high-speed semiconductor fuse standard and IEC 60269-7, a new battery protection fuse standard in development.
