Single Row Terminal Blocks
Single Row Terminal Blocks
General Information:
Single Row Terminal Blocks are available in four basic line to line molding sizes. Some are available in either open or feed
thru/printed circuit designs. The basic material is phenolic. 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.
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
Industrial, general
Ratings based on UL 1059 may be higher in some cases depending on application.
