Double Row Terminal Blocks
General Information:
Double Row Terminal Blocks are available in many line to line spacings. Open and closed back designs are available as shown
in table below. Insulator bases are available in both phenolic and thermoplastic material. Modifications are also provided on most
terminal blocks, including marking strips.
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.
