| Marathon Sectional Terminal Blocks | |
| General information Sectionals are terminal blocks which are made up of individually molded units with electrically conductive members which, when assembled together, make up the block producing the required number of circuits. Marathon offers three sizes of sectional terminal blocks, 3/8" centers and 11/16" sectional fuse holders. All blocks can be ordered with a channel mount base, or a flat mount base for direct mounting to the panel. The 3/8" is also available with a DIN foot. Ratings and Standards The voltage ratings of terminal blocks are based upon the minimum spacing between electrically conductive parts line to line through air and over surface and line to ground through air and over surface. |
