The 387200208: This block mounts to a chassis or panel via the integral flanges — no DIN rail, no PCB footprint. The top termination uses steel screws with a zinc, clear chromate finish; the bottom is closed, so the block terminates the incoming wire only, with no pass-through or daisy-chain path below. The dual-wall barrier design isolates each circuit on both sides, reducing the chance of a stray strand bridging adjacent terminals.
The 8-circuit count matches the number of wire entries one-to-one — each position gets its own screw clamp. If the BOM calls for fewer circuits, the 387200206 is the 6-circuit sibling at the same 0.375" pitch and same 15 A / 300 V rating; it shares the same flange-mount footprint and black UL94 V-0 housing, so a panel laid out for the 8-circuit can accept the 6-circuit with unused positions. For more circuits, the 387200210 is the 10-circuit version. There is also a solder-turret variant, the 387203208, which replaces the closed bottom with insulated turrets for PCB termination — useful if the build shifts from panel wiring to a board-level interconnect.
