The FCI / BergStik® II 79821-456HLF is a 56-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54mm) pitch.
For a 56-position dual-row header, that means the total current through the connector can add up, but the per-contact limit keeps the overall temperature rise under control. The 110 V rating is the working voltage; it's the creepage distance over the unshrouded header that sets that ceiling, so keep the board clean and conformally coat if running near the limit in humid environments.
