Littelfuse POWR-SPEED PSX High-Speed Square Body Fuses
Littelfuse POWR-SPEED PSX Series High-Speed Square Body Fuses are fast-acting devices with high-speed aBat performance in small package sizes. These components are available with multiple mounting terminations: DIN, flush-end, and bolted-blade styles. The PSX series is certified to UL248-13 and offer protection for lower levels of fault current. These fuses are easily detectable in the event of a fault and prevent energy loss, more efficient, and minimize wasted power. The PSX high-speed devices provide superior protection and are optimized for performance and efficiency to help extend equipment life. These fast-acting fuses provide DC interrupting rate of 250kA and a DC voltage rating of up to 1500VDC. The PSX series is designed to protect battery energy storage systems (BESS), photovoltaic inverters, and many DC applications.
