Description

TD power terminal block selection

TD terminal blocks use screw connections in a single bank of 4–16 positions. Each position has paired screw terminals, expressed as 2×(04–16)P in the ordering designation. Select the complete model by pitch, conductor size and mounting dimensions. A covered version with solder pins is also shown for TD2.5/8.4; its pin layout must be specified with that configuration.

Ordering

Specify the model, paired position count, colour and customer requirement suffix. For example, TD2.5/8.4 uses the model segment TD2.5/8.4 followed by 2×XXP, where XX is 04–16. The customer requirement suffix is 00A for the standard designation.
