PSX Series - High-Speed Square Body Semiconductor Fuse
Brand: Littelfuse, IncLittelfuse PSX series 1500 Vdc high-speed square body fuses 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 1,500 Vdc, ranging from 80 A to 1,400 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.
The PSX series is certified to UL 248-13 and compliant with the IEC 60269-7 (Class aBAT) battery protection fuse standard.
Features- High dc voltage rating up to 1,500 Vdc
- DC interrupting rating 250 kA
- Extremely fast acting (high-speed performance)
- Low watt loss (energy efficiency for BESS applications)
