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 the table below. Insulator bases are available in both phenolic and thermoplastic material. Each series
has many hardware and marking options available.
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, including deadfront switchboards, panel boards and service equipment.
Class B:
Commercial appliances including business equipment and electronic data processing equipment.
Class C:
Industrial, general
Reference Chart:
1 Open back terminal blocks require an insulator strip to achieve voltage rating.
2 Wire Range for Bare (unprepared) only. Prepared wire range (used with crimp type ring, fork or spade terminals) is dependent
on the size of the crimp terminal applied and must not exceed the Amp rating specified.
