The 0.400" (10.16 mm) pitch spaces each conductor entry wide enough for 12 AWG wire without crowding adjacent terminals on the board.
Wire Range and Termination — What the Screw Torque Means
The rising cage clamp accepts 12 to 30 AWG wire. The M3 screw is tightened to a specified 0.79 Nm (7.0 Lb-In) — that torque value is not a suggestion; it is the documented clamping force that keeps the brass cage from loosening under thermal cycling. The screw and clamp are both brass with nickel plating, which resists corrosion in industrial cabinet environments. The contact material is brass with tin plating, adequate for the 17.5 A rating at the operating temperature of the PA66 housing.
Current and Voltage — Where This Block Sits in the Power Range
Rated 17.5 A at 600 V, this block handles the majority of control-circuit and small-power-distribution tasks inside an industrial panel. The 600 V rating covers 480 VAC line-to-line with margin, and the 17.5 A per position is enough for a motor contactor coil circuit, a small power supply feed, or a field instrument loop. The interlocking side feature allows multiple blocks to be ganged side-by-side on the same PCB without gaps — useful when building a multi-position terminal strip from 2-position modules.
