Terminal Strip for High-Current Panel Wiring
The Molex Eurostyle 39100 391002504 is a 4-circuit enclosed terminal strip built for chassis or panel mounting. It carries a 63 A current rating per circuit at 600 V — each screw-clamp position handles bus-level load, sized for the main power feed rather than signal wiring. The 0.591" (15.00 mm) pitch gives generous creepage for the voltage rating without crowding the wiring compartment. Top termination uses screws (steel, zinc finish) and accepts wire from 6 AWG down to 14 AWG — thick enough for a 63 A feeder. The bottom is closed, meaning the strip mounts directly to the panel with no through-hole solder tails; the enclosed barrier style protects against accidental contact and debris ingress. The white polyamide (PA66) housing is rated UL94 V-0 for flame retardance, and the operating temperature range spans -40°C to 105°C. This combination suits industrial control cabinets, power distribution panels, and outdoor telecom enclosures where high current and environmental range are required.
Circuit Count Comparison
The 391002504 carries 4 circuits. The same-series 391002505 offers 5 circuits at the same 0.591" (15.00 mm) pitch, same 63 A / 600 V rating, same screw top and closed bottom. The 391002503 is the 3-circuit sibling. The choice comes down to position count matching the BOM — the footprint and wiring pattern are identical per circuit, so swapping between them only changes the number of wire entries (8 for the 4-circuit, 10 for the 5-circuit, 6 for the 3-circuit).
