How to Order
CFT Series terminal blocks are ordered by listing designation followed by the number of poles required for the application. Example: Type CFT 10-pole block becomes stock number CFT-10.

Suffixes are used as follows:
W C A	Denotes model with wire clamp replacing external screw terminal. Denotes model less mounting positions. Denotes model with 8-32 terminal (CBP only).

To specify quick-connect terminals, simply add the style number required

May be purchased factory-assembled or as customer-installed accessory.

The CFT-10 described above with wire clamp less mounting positions thus converts to stock number CFTWC-10.
