NLS series fuses provide low cost protection for general-purpose feeder and branch circuits when available short circuit currents are less than 50,000 amperes. They replace all Class H fuses which have only a 10,000 ampere interrupting rating. They are suitable for use in many residential and smaller commercial and industrial applications. NLKP series fuses are Canadian “Code” fuses specifically designed to meet Canadian Electrical Code Type P fuse requirements for residential use. They have a 10,000 ampere interrupting rating. However, to obtain the added benefits of time-delay, current-limitation, and higher interrupting rating, consider the use of POWR-PRO™ IDSR Indicator™ fuses for circuits between 250 and 600 volts. The user gets all the benefits of time-delay RK5 fuses plus the added benefits of a n indicating fuse that tells when it has opened. Complete information on these fuses may be found in the POWR-PRO™ section of this catalog. For circuits up to 250 volts, see FLNR fuses in this section of the catalog.

Littelfuse DIN series midget fuse blocks have integral DIN rail mounting capabilities that allow secure mounting to 35mm DIN rails. New releasable mechanism allows installation and removal of block without removing adjacent components on DIN rail. Electrical panel builders and machine builders no longer need to use mounting adapters, saving assembly time and related costs.

The SMBJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The new Littelfuse Class T fuse blocks offer many advantages over previous generations that are noted in the features and benefits section. Of particular value is the space savings these new blocks provide. Features/Benefits:

The Littelfuse® POWR-PRO® JTD_ID Indicator Class J fuse provides visual blown fuse indication and maximum protection in a compact package. The compact Class J package was designed specifically for circuits where space is at a premium. The current limiting time delay JTD_ID offers a patented true dual-element design that is ideal for use in circuits with high inrush currents. Superior performance characteristics of JTD_ID Indicator fuses reduce nuisance fuse opening and the blown fuse indication reduces downtime and increases safety. Applications:

The Littelfuse Industrial TMOV34S® series thermally protected varistor represents a new development in circuit protection.It consists of a 34mm square format varistor element ( MOV) with an integral thermally activated element designed to open in the event of overheating due to abnormal over-voltage, limited current conditions. Certain TMOV34S devices are offered with a "monitor" lead which may be connected to signalling circuity to indicate if the MOV has been disconnected from the circuit. TMOV34S Series devices offer quick thermal response due to the close proximity of the integrated thermal element to the MOV body. The integrated configuration also offers lower inductance than most discreet solutions resulting in improved clamping performance to fast over voltage transients. UL1449 3rd Edition approval of TMOV34S Series is currently pending related to the integrated thermal element of this series.
