Littelfuse is a global manufacturer of leading technologies in circuit protection, power control and sensing. After decades of innovation and through strategic acquisitions, they have developed the broadest circuit protection portfolio in the world. Littelfuse products offer protection against power surges, electrostatic discharge, voltage spikes, short circuits, arc flash and other harmful occurrences. Littelfuse manufactures the most innovative and widest selection of fuses to serve nearly every application. RSP Supply is a proud distributor of Littelfuse time delay and fast-acting fuses. Time delay fuses will carry an overload for a short period of time without blowing. These fuses are ideal for situations where acceptable momentary overloads are encountered, such as starting a motor. Fast-acting fuses blow immediately after the maximum rating of the fuse is exceeded. These fuses are ideal for protecting sensitive equipment.
