The 395430003: The 5.00 mm pitch sets the board footprint — three holes on 5.00 mm centers, with the wire entry parallel to the board. That horizontal orientation matters when the enclosure height is tight; the wires run flat against the PCB rather than standing up. The 10 A per-position rating is the thermal limit at the stated ambient; in a crowded cabinet running at 55°C, derate that figure. The 300 V rating covers most control and low-power distribution circuits. The recommended screw torque of 0.34 Nm (3.0 Lb-In) is enough to clamp the wire without stripping the steel screw or cracking the PA66 housing.
Termination and wire handling
The screw termination uses a leaf spring and wire guard — the guard prevents the screw from biting into individual strands, which is the failure mode that causes intermittent opens on stranded wire in a vibrating panel. The 14-24 AWG range covers common control wiring: 14 AWG for short power runs, 18-22 AWG for signal and sensor wiring.
