Series GFT/GB 7/16" (11.11mm) Center-to-Center Spacing
Features:
Superior Construction – All terminals are molded in place
with precision screw machined brass inserts which will not
twist Yirtually eliminating broNen solder Moints while proYiding
a full mechanical thread system.
Ideal for Sub-Chassis or Thru-Panel Application –
No costly insulation or mounting set-up since feed-thru
insulators are an integral part of the moldings. Feature
provides a full 1/4" terminal to ground clearance even thru
1/16" chassis.
Durable Base Material – Made of black thermo-set
phenolic, or high-impact, break-resistant thermoplastic
Electrical Rating – 20A up to 600V
Compact Barrier-Type Design – Especially suited for
electronic and control applications
Feed-Thru, Printed Circuit or Surface Connection – One
thru 26 terminals on 7/16" center-to-center spacing
Broad Wire Range – UL recognized for No. 22AWG to No.
12AWG, depending on type of external contact designated,
with CSA requiring use of lugs on wire larger than No. 16AWG.
Terminal Flexibility – External terminals available in two
screw sizes with various internal terminal types
Recognition and Listing – UL recognized and CSA certified
Recognized under the Components Program of
Underwriters Laboratories, Inc. Standard 1059,

How to Order
GB/GFT Series terminal blocks are ordered by listing a
composite number made up of the model designatin followed
by the number of poles required for the applicaiton. Example:
Type GBP 10-pole block becomes stock number GBP-10.
Suffixes are used as follows:
A denotes model with No. 8-32 external screw
terminal
C denotes model less mounting positions
X denotes model with thermoplastic molding
To specify quick-connect terminals, simply add the style
number required. May be purchased factory-assembled or
as customer-installed accessory.
The GBP-10 described above – made from thermo-set
phenolic – less mounting positions thus converts to sock
number GBPC-10.
