How to Order
Types L, O and S terminal blocks are ordered by listing a
model number made up of the series designation followed by
the number of terminals required for the application .
Example: a 4-pole terminal block becomes L-4, 0-4 or S-4
When ordering combinations of both types, the model
number is made up of both series designations followed by
total number of poles and number of each type . A model
number of two L terminals followed by two O terminals thus is
converted to stock number LO-4 (2L, 2O) .
Combining these types with types T, U, S, H and BT would
follow the same ordering format . ( Note: When combined with
types H or BT, a special adapter is required .)
