How to Order
Types T and U terminal blocks are ordered by listing a
composite number made up of the model designation followed
by the number of terminals required for the application .
Example: a 4-pole terminal block becomes T-4 or U-4
When ordering combinations of both types, the composite
number is made up of both model designations followed by
total number of poles and number of each type . A composite
of two T terminals followed by two U terminals thus is
converted to stock number TU-4 (2T, 2U) .
Combining these types with types L, O, S, H and BT would
follow the same ordering format . ( Note: When combined with
types H or BT, a special adapter is required .)
