Modular, Color-Coded Terminal Blocks
Modular, Color-Coded
Terminal Blocks
Never content to sell the same old blocks, we at BlockMaster
have pushed the envelope yet again with another innovative
series. This time
we’re
targeting a very important segment of
our customer base: the field engineers.
We’re
sure
they’ll
be
happy to know that with our two lines of Jelly Beans terminal
blocks,
they’ll
never again have to worry about the age-old
problem of incorrect field wiring. Both products can have a
different color for each position, helping to eliminate
installation mistakes.
The JB Series are modular, barrier-style terminal blocks that
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. Single circuit modules snap
together to form nearly infinite circuit configurations, and each
position can be any of ten available colors. Standard design
features include break-resistant 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 7/16” (0.437” or 11.1 mm).
Eliminate the Problem of
Field Installation
Mistakes!
