Ordering Part Number Variable frequency drives, inverters, UPS, rectifiers, and soft-starters are examples of typical equipment designed PSR 030 US 0550 Z with sensitive power semiconductor devices that cannot withstand any line surge or overcurrent conditions and Series require high-speed protection. Case Size Packing Quantity The PSR series with bolted blades is designed and tested 30, 31, 32, 33, 70, 71, 72, 73 X = (1 pc/box) to IEC 60269-4. Z = (3 pcs/box) Termination Amperage Littelfuse POWR-SPEED PSR series products offer US = bolted short blade optimized circuit protection at the extremely fast speed UL = bolted long blade required to protect modern day power conversion devices. Available in bolted blade style termination (typical in North American market) with visual blown fuse indication standard Catalog Number on all fuses and optional micro-switch for external indication.
