Top termination: captive-plate screw clamp
The 386345108: The top termination uses screws with a captive plate — the plate distributes clamping force across the conductor cross-section so that 12-24 AWG wire is held without the cold-flow creep that a bare set-screw onto a single wire can cause over thermal cycling. The terminal screw material is steel with a zinc clear chromate finish, which handles the panel environment but is not the same as nickel or stainless; in highly corrosive atmospheres a plated lug or ferruled termination is the practical workaround. The 8 wire entries match the 8 circuits one-for-one, so the entry count is not a derating factor.
Bottom termination and board mounting
Bottom termination is a PC pin — the connector mounts through-hole on the panel or PCB, and the pin solders into the board for a permanent electrical through-path. The single-row layout with 0.438-inch pitch and through-hole mounting gives a board footprint specific to the 38634 series.
Ratings that drive the BOM decision
The 20 A per circuit at 600 V rating is the headline pair for this part, but the wire gauge range of 12-24 AWG is equally load-bearing: 12 AWG gives the full 20 A headroom, while 24 AWG is physically accepted but the current density in the conductor itself becomes the limit before the connector does.
