Description

Littelfuse PSX series 1500 V dc high-speed square body

fuses are specially designed to protect battery energy

storage systems (BESS), photovoltaic inverters, and many

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, DIN, and bolted-blade styles. Visual

blown fuse indication is standard on all fuses and optional

micro-switch is available for external indication.

The PSX series is certified to UL248-13 and designed to

meet IEC 60269-7 (Class aBat) battery protection fuse

standard.
