The locking ramp on the header engages the positive latch on the plug housing."},{"question":"What is the current and voltage rating of the 770143-1?","answer":"12A per circuit at 600VAC. The per-contact rating assumes a single circuit carrying full current; thermal management of the housing sets the practical system limit when multiple circuits share a load path."},{"question":"What is the pitch of the 770143-1?","answer":"0.250 inch (6.35 mm). The wider pitch compared to signal-density connectors gives the 770143-1 the current headroom needed for power distribution rather than signal switching."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/770143-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/770143-1 when reusing this data.
