KLLU UL CLASS L TIME-DELAY FUSE 750A. KLLU series UL Listed, time-delay, Class L are quality fuses in every sense of the word. They were developed to provide a somewhat lower priced alternate to the POWR-PROÖ KLPC series fuses. KLLU series fuses meet or exceed all UL requirements for Class L fuses. For superior protection and performance, specification-grade POWR-PROÖ KLPC series fuses are the recommended fuses. Applications: Service switches. Switchboard mains and feeders.Bolted pressure contact switches. Motor control center mains. Large motor branch circuits. UL Listed series-rated protection for molded case circuit breaker panelboards and loadcenters. See panelboard manufacturerÆs literature for recommended fuse rating. Safety: 200,000 A.I.R. ù Provides reliable interruption of all overcurrents up to 200,000 amperes. When used for motor branch circuit protection, KLLU fuses may be sized close to the motor full-load current, providing excellent protection to branch circuit conductors, motor control equipment and motors. Longer Equipment Life: Current limiting ù Reduces short circuit damage to systems and equipment. Reduced downtime Ten second minimum time delay at 500 percent of rating eliminates needless downtime caused by heavy starting currents of large motors and other inductive loads. Selective coordination ù KLLU fuses coordinate well with other Class L fuses and with all current-limiting Littelfuse fuses rated 600 amps or less. This means less time spent trying to locate short circuits or overloaded equipment, because only the fuse immediately on the line side of the affected circuit opens. Easy to Use: 200,000 A.I.R. rating minimizes need for short circuit calculationsàmeets present and future system requirements. KLLU fuse time-current characteristics closely match typical time-current curves of circuit breakers. Although fuse/circuit breaker systems can seldom be 100percent coordinated , KLLU series fuses permit use of a wider range of breaker setting than fast-acting Class L fuses. Excellent protection for a single breaker or a group of breakers.

NLN UL CLASS K5 ONE-TIME FUSE 110A. NLN 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 ôCodeö 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-PROÖ IDSR IndicatorÖ fuses for circuits between 250 and 600 volts. The user gets all the benefits of time-delay RK5 fuses plus the added benefits of an indicating fuse that tells when it has opened. Complete information on these fuses may be found in the POWR-PROÖ section of this catalog. For circuits up to 250 volts, see FLNR fuses in this section of the catalog. Applications: General purpose residential and commercial circuits with little or no motor load. Resistive heating loads. Economical: For use in applications where lowest initial cost is the major consideration. Safety: 50,000 A.I.R., Class K5 ù Adequate interrupting capacity for residences and many smaller facilities.

KLKR UL CLASS CC FAST-ACTING FUSE .300A. KLKR series Class CC fuses are fast-acting fuses intended for general-purpose branch circuit protection. Their compact size, fast-acting overload response, and their highly current limiting design make them ideal for use in OEM equipment and control panels because. Solid-state devices such as SCRs and other electronic equipment generally require fast-acting protection. Compared to other UL Listed fuses, Class CC fuses are the most current limiting, rating for rating. Provide superior protection in a fraction of the space required by other fuse classes. For example, when 600 V three-pole, 30 A Class R fuse blocks are replaced by Littelfuse Class CC fuse blocks, panel-mounting space is reduced approximately 70percent.General purpose protection of equipment requiring fast overload protection û KLKR series, fast-acting fuses used for protection of equipment containing solid-state devices or other electronic components requiring fast response on overloads. 200,000 A.I.R. ù Reliable interruption of all overcurrents up to 200,000 amperes. Extremely current limiting ù Reduces damage caused by heating and magnetic effects of short-circuit currentsàstops damaging short-circuit faster than any mechanical protective device. Space Saving: Class CC fuses are the smallest 600V, 200,000 A.I.R. fuses approved for branch circuit protection.

One-Time OT and OTN general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. OT and OTN fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings. OT and OTN fuses are not rejection fuses and care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses. OTN(15-60) satisfy the Canadian electrical code requirement for Type P low melting-point, non-time-delay fuses. 250 Volts 25 amps OT series.
