Eurostyle 39910 3-Position PCB Terminal Block
The Molex 399100103 is the 3-position member of the Eurostyle 39910 series — a through-hole PCB terminal block rated 60 A per circuit at 600 V, with screw rising cage clamp termination for 6-18 AWG wire.
Termination and Installation
Operating range is -40°C to 130°C, and the black thermoplastic housing carries a 1-level configuration — single-tier contact stack, no stacking. The horizontal board orientation places the wire entry perpendicular to the PCB plane, which affects panel cutout depth when routing the harness.
39910 vs 39970 — Voltage and Position Count
The 39970 series shares the same 0.400" (10.16 mm) pitch, 60 A rating, and through-hole mounting as the 39910, and uses the same screw rising cage clamp. The 0399700104 carries 4 positions and is rated 300 V — half the voltage of the 399100103. If the panel was specced around 0399700104, the voltage differential is the gating constraint: a 600 V system needs the 39910, not the 39970. Position count also differs (4 vs 3), so rewiring is required for a direct swap if the application needs the extra circuit.
