BUCHANAN Terminal Blocks Fuse & Switch Product Facts High Density Blocks n Fuse and Switch Blocks rated 15A and 300V. n High Density 0.36" [9.14] centerline spacing saves panel space; at least 33 circuits per foot. Fuse Blocks n Provide NEMA Terminal Blocks in-line circuit protection for virtually any circuit or group of circuits — select contacts for terminated or unterminated wire. n Remove, check and replace fuses safely and quickly — switch action fuse blocks open circuits before fuse can be removed or installed. n Contacts conservatively rated to 30 amperes. 6 Switch Blocks n Quickly and easily interrupt a circuit or group of circuits — insert switch blocks directly in line. Contacts available for terminated or unterminated wire. n Keep circuits open for extended periods — switch blade can be removed entirely from block for lockout protection. n Rated to 15 amperes. Common Features of 300 & 0300 Series n At least 91 circuits per 6-foot length, 3/4 inch center-tocenter spacing. n Blocks meet 600 volt clearance and creepage spacings specified in UL, CSA, and NEMA Industrial Control Standards. n Choose nylon housing material — for more rugged applications; polypropylene for fire retardant characteristics. n Dovetail base fits standard mounting channel — can also be mounted on flat surfaces. n Only one end section needed per block assembly. n Readily identify circuits — mark directly on white, matte-surface puller assembly, marking tab on block, or use removable marking tape. n Open or close several circuits simultaneously — holes in puller handles allow use of nylon “ganging” rods. n Fuse and Switch block sections snap-fit with 300 & 600 Volt, phenolic Medium Duty, Heavy Duty, and Intermediate Heavy Duty blocks. This broad line features High Density Blocks (Series 0135), Nylon & Polypropylene Blocks (Series 0300) and Phenolic Blocks (Series 300).
