General Information:
Barrier Style Power Terminal Blocks are available in eight sizes. They are identified by the first three digits of the catalog number. The
140, 142, 143, 144 and 145 series are manufactured with general purpose phenolic rated at 150
are manufactured with high impact thermoplastic rated at 125
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.
Power Terminal Blocks
Applications:
Designed for use with solar, wind, alternate energy, transportation, heating, air conditioning and refrigeration, elevator systems,
material handling equipment, control panels, motor control, switchgear and any area where power needs to be distributed to more
than one load.
