It carries a 0.394\" (10.00mm) pitch — wide enough for the 10-18 AWG wire range it accepts — and is rated 30A at 300V. Top termination uses screws with a zinc finish on steel; the bottom is closed, meaning the screw terminals are only accessible from the top side once the block is mounted. The 30A per-circuit rating is the headline number — this terminal strip carries power, not signal. At 300V, the 0.394\" (10.00mm) pitch provides enough creepage for that voltage without forcing an oversized board footprint, but this is a panel-mount block, not a PCB-mount one. The 10-18 AWG wire range covers typical motor, heater, and power-supply leads; the closed bottom means you terminate from the top only, so plan access for a screwdriver above the block. The 391002103 shares the same 0.394\" (10.00mm) pitch, 30A current rating, 300V voltage, chassis/panel mounting, and white PA66 UL94 V-0 housing with the 12-circuit 391002112.","metaTitle":"Molex Eurostyle 391002103, 3-Circuit 30A Terminal Strip","metaDescription":"Molex Eurostyle 39100 391002103, 3-circuit enclosed terminal strip, 0.394\" (10.00mm) pitch, 30A at 300V, 10-18 AWG, white PA66 nylon, UL94 V-0.
