Fuses Handle High Voltages
Coming in a 5 mm × 20 mm ceramic package, Littelfuse’s 477 Series time-lag cartridge fuses demonstrate a voltage rating of 500 V at 8 A or above. The RoHS-compliant devices exhibit ampere ratings from 0.5 A to 16 A, an interrupting capability of up to 1,500 A at 400 VDC, and recognition from UL, CSA, and SEMKO. The products are appropriate for 3-phase power supplies, uninterruptable power systems (UPSs), motor control circuits, and air conditioning units. The fuses can be used before and after the PFC capacitor banks for individual component and secondary circuit protection.
