The BlockMaster JB Series Terminal Blocks offer color-

ful ways of solving field wiring problems. Single circuit

modules snap together to form nearly infinite circuit con-

figu

rations. If desired, the modules may be separated with a

special tool. Standard design features include break resis-

tant barriers, standoffs for flux cleaning and ready-to-wire

screws. A full range of terminal configurations are offered

on industry standard center to center spacings of 3/8” -

(0.375” or 9.50 mm) and 7/16” - (0.4375” or 11.11 mm).

BlockMaster JB series terminal blocks offer the ability to

color code each terminal to match customer wiring. This

allows for the separation of line voltage from signal inputs

and outputs.

Block configurations are available assembled to your specs

or in packages of 100 single circuit modules (with appropri-

ate end barriers or end mounting).
