Applications:
Designed for electrical termination of wire where flexibility of circuit design is necessary. Accepts single or multiple wire
sizes for tubular screw and tubular clamp styles.
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’s DIN
Sectional Blocks will fit on a standard 35mm DIN rail.
Marathon offers three sizes of sectional terminal blocks: 3/8” centers, 7/16” centers, 1/2” 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; alternatively, the 7/16” is only 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.
Class A
Service equipment including deadfront switchboards, panel boards, service entrance devices.
Class B
Commercial appliances including business equipment, electronic data processing equipment and the like.
Class C
General industrial and machine tool controls which can be further defined as equipment falling under UL 508.
