What this block is
The Molex 393570006 is a single-level, 6-circuit Eurostyle 39357 terminal block in black nylon, sized for 16–28 AWG wire. It uses a screw-rising cage clamp — the wire seats in the cage and the screw draws it tight without pre-ferrule or special preparation. Rated 12 A per circuit at 300 V with an operating range of -40 °C to 105 °C. Mount is through-hole, horizontal with the board.
What the ratings mean for your fit
The 3.50 mm pitch sets the board footprint and the routing density — this is a compact panel or DIN-rail block, not a high-current distribution post. The 12 A per circuit rating is governed by the tin-plated contact and the nylon housing's temperature rise limit; above 105 °C the housing exceeds its rated envelope. The M3 screw torque spec of 0.31 Nm applies to the clamp screw — not a separate strain-relief thread — so torque to spec or the clamp grip on fine-stranded wire will be inconsistent. The nickel-plated clamp body and nickel-plated screw resist corrosion under panel humidity better than bare brass; the tin plating is on the contact where it is standard for signal-level or light-power interconnections. This is an industrial-duty block for control-cabinet or DIN-rail use — the series is not a PCB pin-header strip but a wire-entry block with a through-hole lead for board soldering.
