Blocks and Holders Semiconductor Fuse Blocks Recommended Fuses Semiconductor fuses. See tables below. LSCR001 Semiconductor fuse block selection guide Modular-designed Semiconductor fuse blocks are designed to accommodate a wide range of Semiconductor fuses, with a maxi mum diameter of 3". This modular design greatly reduces inventory requirements. They are sold in pairs and are constructed of molded phenolic, with plated steel studs. 1.88" 1.30" 0.70" LSCR001 0.203" x 0.30" SLOT Blocks and Holders 1/4-20" x 1.00" USABLE LENGTH 2.38" 1.34" 0.25" 2.13" 0.203" x 0.30" SLOT 1.60" 1.00" LSCR002 1.00" Ampere Rating L15S L25S, LA30QS L25S L50S, LA50QS L50S, LA50QS L50S L60S L60S L60S L70S, LA70QS L70S, LA70QS KLC KLC LA100P 70 - 400 35 - 60 70 - 200 35 - 60 70 - 100 125 - 200 35 - 60 70 - 100 125 - 200 35 - 60 70 - 100 1 - 30 35 - 60 35 - 60 LSCR002 Semiconductor fuse block selection guide 0.70" 0.50" Fuse Series 0.50" Fuse Series Ampere Rating L15S, LA15QS L25S, LA30QS L25S, LA30QS L50S, LA50QS L50S, LA50QS L50S, LA50QS L60S L60S L60S L70S, LA70QS L70S, LA70QS L70S, LA70QS KLC KLC KLC KLC LA100P JLLN 500 - 800 225 - 700 800 225 - 400 450 - 600 700 - 800 225 - 400 450 - 600 700 - 800 125 - 200 225 - 400 450 - 800 70 - 100 125 - 200 225 - 400 450 - 800 70 - 800 700 - 1200 Specifications 0.75" Voltage rating: 3/8-16"x1.00" USABLE LENGTH 3.44" 2.44" 0.25" 0.50" 134 LSCR001: Accepts fuses 1" diameter or less at 600V.
