It uses a screw rising cage clamp to terminate 16-30 AWG wire against a tin-plated copper alloy contact, with the wire entry oriented horizontal to the board. The 5.00 mm pitch gives enough spacing for the 300 V rating without crowding adjacent traces, and the 13.5 A current rating covers most industrial control and lighting circuits. The black polyamide housing carries the interlocking side feature so you can gang multiple blocks on a rail without losing alignment. The 13.5 A and 300 V ratings are the electrical limits; derate above 105 °C per the product drawing. ## Where It Goes Single-level, 3 positions per level, through-hole mounting. The interlocking side feature lets you snap multiple 39890 blocks together side-by-side for more circuits on the same rail, keeping the screw rows aligned. Typical use is power distribution and signal termination inside industrial cabinets, HVAC controllers, and lighting ballast enclosures.","metaTitle":"Molex Eurostyle 39890 398900303, 3-Pos 5mm PCB Terminal Block","metaDescription":"Molex 398900303 Eurostyle 39890 terminal block, 3 positions, 5.00mm pitch, 13.5 A, 300 V, screw rising cage clamp, 16-30 AWG, through-hole, black.
