What it is — 4-position top-entry terminal block, 5 mm pitch
The Molex Eurostyle 39700 397000904 is a 4-position, single-level PCB terminal block with a 0.197" (5.00mm) pitch. Wires enter vertically (top-entry) and terminate with a screwless push-button clamp — no tool needed to insert or release 14-22 AWG solid or stranded wire. Rated 10 A per position at 300 V, with tin-plated brass contacts. The push-button clamp holds the wire against a stainless-steel spring — the clamp material is steel, stainless, so it resists corrosion in humid cabinet environments.
That's tight enough for a compact layout but leaves room for routing a 300 V trace between positions. The 10 A rating is per position at the stated temperature rise; derate above 105°C per the product drawing. 14-22 AWG covers most panel wiring — solid for permanent runs, stranded for flex. The push-button clamp accepts both; it's a spring clamp, not a screw clamp, so it's best for installations where vibration is low. Green housing is a visual cue on the board — some panel builders use green for ground or safety circuits, but there's no standard. The colour is just the moulding pigment; the PA66 material is the same as the black variant in the series.
