It carries a 30 A per circuit rating with a 630 V voltage rating, placing it in the power-header class — not a signal interconnect.
The tin-plated solder tails are standard for through-hole wave solder and keep the cost down where the contact finish matters less. The detent lock gives a positive tactile and audible click on mating, which is useful in field-service and harness-assembly environments where a friction-only fit might feel ambiguous. The UL94 V-0 flame rating is a regulatory requirement for connectors inside equipment enclosures — it confirms the housing will self-extinguish in a fault condition. The IP20 ingress protection rating means the header is finger-safe but not sealed against moisture or dust — this is an indoor, dry-location connector. For sealed applications, a different connector family with an IP67-rated housing would be needed.
The Dynamic D-5200 series covers single-row headers from 2 to 12 positions at the same 0.400 inch pitch and 30 A per circuit rating. The 3-position 2-353081-3 is the smallest practical power header in the series — it fits a 3-circuit BOM line for a single-phase input or a small DC rail. The 2-position variant (2-353081-2) exists for a two-wire line, but the 3-position is the more common choice because it gives a dedicated ground or neutral alongside the two power conductors.
