Terminal Strip for Panel-Mount Power Distribution
The Molex Eurostyle 39100 391001905 is a 5-circuit enclosed terminal strip designed for chassis or panel-mount power distribution. It carries a 20 A per-circuit rating at 300 V, with the 8.00 mm pitch providing enough spacing for 12-22 AWG wire terminated under the top screws.
5 Circuits vs 6 — the Circuit Count Decision
This 5-circuit strip (391001905) shares the same 8.00 mm pitch, 20 A rating, and screw termination as the 6-circuit 391001906. If the BOM calls for 5 circuits, this is the direct match; the 6-circuit version adds one extra position that would leave a terminal unused in a 5-circuit layout. Both mount to the same panel cutout pattern, so swapping between them requires no enclosure modification, only a circuit-count check on the schematic.
Top termination uses steel screws with a zinc finish, clamping down on 12-22 AWG wire. The bottom termination is closed — no through-panel feed-through — so all connections are made from the top side. The enclosed barrier type provides physical isolation between adjacent terminals, reducing the risk of accidental shorting during field wiring. Mounting is via chassis or panel holes; the strip does not require a DIN rail.
