It sits in the RAST 5 series at a 5.00 mm pitch, carrying a 16 A per-circuit rating that puts it in power-distribution duty — think appliance main boards, lighting ballasts, or HVAC control panels where you need a locked, shrouded header that won't let a wire pull loose. The 250 VAC rating and UL94 V-0 nylon 6/6 housing suit it for equipment inside an enclosure where flame rating is required.
What the 16 A rating means for your build
16 A per circuit on a single-row 5.00 mm pitch header is a solid power rating — each tab is sized to carry the main DC rail or an AC load circuit, not a signal line. The 250 VAC rating gives you mains-voltage isolation headroom.
