Terminal Block Overview
The Molex Eurostyle 39880 398800504 is a 2-position, 2-level PCB-mount terminal block on 5.08 mm pitch. It terminates wire via a screw-actuated rising cage clamp — the clamp lifts against the conductor as the M3 screw is torqued to 0.68 Nm, creating a gas-tight connection for 16-30 AWG solid or stranded wire. The side-entry wire orientation keeps the block low-profile when routing conductors parallel to the board. Rated 13.5 A at 300 V, with a -40°C to 105°C operating range, this block suits power distribution and control wiring inside industrial cabinets, HVAC panels, and outdoor telecom enclosures where the wide temperature margin covers unheated spaces. The polyamide (nylon) housing carries a black finish, and the interlocking side feature lets multiple blocks key together on a rail for multi-circuit layouts.
Two-Level Construction — Density Without a Bigger Footprint
With 2 positions per level across 2 levels, this block terminates four wires in the board footprint of a single-level 2-position block. The staggered screw access keeps the tool clearance manageable — you can reach both levels with a standard screwdriver without removing adjacent wiring.
