Blocks and Holders In-Line Watertight Fuseholders Littelfuse 600 volt in-line watertight fuse holders are the ideal answer for all high humidity and corrosive environments where fuses are required. Available in both breakaway and non-breakaway, single and double pole versions, these fuseholders allow maximum flexibility for any application. Applications Street, alley, and parking lot lighting Security and perimeter lighting Traffic signals Outdoor illuminated signs Sports lighting Boat electrical circuits Tractors and yard equipment General outdoor circuit protection Benefits Features Blocks and Holders TO SOURCE ELECTRICAL TAPE TO LOAD * Safety -- Permits individual fixture or device to be disconnected from circuit for servicing. Eliminates possibility of shock. * Individual fixture fusing -- Prevents loss of one fixture through accident, vandalism, or end of life from darkening the entire circuit. * Simplifies maintenance -- Being able to immediately identify the one faulted fixture eliminates testing the entire circuit, speeds repair, and allows the individual unit to be serviced while the rest of the circuit is functioning. * Reduces damage from fault -- Can prevent faulted ballast or other failure from severely damaging fixture or device, reducing necessary repair or need of replacement. * Watertight -- Internal O-ring provides watertight seal. * Superior terminal seals -- Ultrasonically-welded terminals provide maximum strength and eliminate leaking at terminals. * Break resistant -- Fiberglass reinforced polymer body resists damage from dropping or impact much better than phenolic look-alikes. * Flexible terminations -- Accommodates a wide range of stranded or solid copper or aluminum conductors. Terminations are available for one or two conductors, with either crimp or screw terminals. * One-pole and two-pole models available to accommodate all system voltages up to 600V.

Littelfuse types KLKR, KLDR and CCMR. 145 Blocks and Holders In-Line Watertight Fuseholders LEB/LEC One-pole LEB and LEC Fuseholders Basic single-pole LEB and LEC watertight fuseholders provide protection for a variety of circuits. LEB fuseholders accept all 13 32 / " x 11/ 2" midget fuses providing supplemental overcurrent protection. LEC fuseholders are UL Listed Class CC fuseholders which accept only Class CC fuses and meet National Electrical Code requirements for branch circuit protection. The most common use for either fuseholder is for protection of lighting circuits. However, consider them wherever there is a need for secure in-line protection, from boat circuits to electric wheelchairs. Great flexibility is achieved when the basic holders are combined with breakaway receptacles, Y-terminals and insulating boots. LEX/LEY Two-pole LEX and LEY Fuseholders LET LEX and LEY fuseholders are intended for use on line-to-line circuits up to 600 volts and are ideal for line-to-line loads such as 240 or 480 volt ballasts. When the line and load sections of LEX and LEY fuseholders are separated, or when the fuseholder is removed from a two-pole breakaway receptacle, both lines are disconnected simultaneously. This prevents the possibility of shock from backfeeding through an exposed fuse, which could happen with single-pole fuseholders. The LEX holder is a two-pole version of the LEB and accepts midget fuses, providing supplementary overcurrent protection. The LEY holder is a two-pole version of the LEC, which accepts only Class CC fuses, and may be used to provide branch circuit protection. Both fuseholders may be equipped with Y-terminals, breakaway receptacles and insulating boots. One-pole LET Solid Neutral Disconnects Blocks and Holders The LET solid neutral disconnect is designed for use as a no-load non-fused disconnect. Similar in design to the LEB series fuseholders, the LET is easily identified by its all white body. Internally, it has a permanently installed solid tin-plated copper neutral slug which eliminates the possibility of placing a fuse in the neutral side of the circuit. Fusing the neutral side causes a safety hazard and also violates the National Electrical Code. The LET is available in both breakaway and non-breakaway configurations with a wide variety of terminations. Breakaway Feature Breakaway 146 Littelfuse LEB, LEC, and LET single-pole fuseholders and LEX and LEY two-pole fuseholders are available with an optional breakaway feature required to meet state and federal highway commission standards requiring fuseholders to readily disconnect from the line in case of a pole knockdown. The breakaway feature consists of a receptacle permanently attached to the power line and a fuseholder with matching terminals. When knockdown occurs, the parts separate readily. The breakaway receptacle terminal is deeply recessed so that energized parts are not exposed. The fuse remains safely enclosed inside the now de-energized watertight fuseholder. After the pole has been reinstalled, the fuseholder is easily plugged into the receptacle, immediately restoring service. The breakaway feature may also be used in marinas, travel trailer parks and other locations where circuits subjected to strain must be safely disconnected. www.littelfuse.com (c) 2005 Littelfuse * POWR-GARDTM Products Catalog Blocks and Holders In-Line Watertight Fuseholders WPB1 BOOT (OPTIONAL) A & B Crimp Terminal WPB1 BOOT (OPTIONAL) 4.5" 9.3" ( ASSEMBLED LENGTH ) C & D Crimp Terminal INSULATING BOOT (STANDARD) J Terminal INSULATING BOOT (STANDARD) 4.5" 5.4" ( ASSEMBLED LENGTH ) 10.3" ( ASSEMBLED LENGTH ) Y Terminal Insulating Boots Molded from engineering grade thermoplastics, the WPB1 and WPB2 provide a high resistance to cor rosive environments and deliver a watertight seal. Boots are supplied as standard with all breakaway versions. Weatherproof boots WPB1 and WPB2 can be purchased separately for all non-breakaway holders. Part number WPB1 contains one standard boot for use with A, B, C, D, or J termination. Part number WPB2 contains one Y-pole boot for use with the Y-pole termination. For watertight protection of non-breakaway Y-pole fuseholders, order one WPB1 and one WPB2 boot. For non-breakaway double-pole LEX and LEY holders with A, B, C, D, or J terminations, order four WPB1 boots. These insulating boots are designed to fit snugly onto wire insulation, but for best results with varying wire insulation sizes, a tape wrap should be completed. 4.5" 9.3" ( ASSEMBLED LENGTH ) Blocks and Holders 4.2" 5.3" ( ASSEMBLED LENGTH ) 10.3" ( ASSEMBLED LENGTH ) Recommended Crimping Tools Terminal Size T&B Part No. Burndy Part No. A B C D WT161M WT161M WT115A WT115A - MR4C Hypress Y34A Hypress Y34A The following crimping tools or equivalents may be used on either the non-breakaway or breakaway watertight in-line fuseholders.
