DOUBLE ROW TERMINAL BLOCKS

TERMINAL BLOCKS

DOUBLE ROW TERMINAL BLOCKS come in three basic options dependent on base material and style:

• CLOSED BACK, THERMOPLASTIC - the ideal option for standard configurations. Generally, these are the most

cost effective and are more robust than any other style.

• CLOSED BACK, PHENOLIC - this is the second best option for standard configurations where temperature

ratings are between 125° C and 150° C.

• OPEN BACK, PHENOLIC - should be used only for feed-thru hardware options, and requires an additional

insulator strip in order to attain the noted voltage rating.
