In practice, with 22 AWG wire and the matching receptacle contact, expect around 4-5 A per circuit at a 30°C temperature rise. The 250VAC voltage rating is fixed and matches common line-voltage lighting and general-purpose power distribution. ## Mates with CST-100 receptacle housings The 3-644892-8 is the board-mounted half of a wire-to-board connection. It mates with CST-100 receptacle housings that accept 22-26 AWG crimp terminals.","metaTitle":"3-644892-8 TE Connectivity CST-100 Header 8 Pos 2.54mm","metaDescription":"3-644892-8 TE Connectivity CST-100 shrouded header, 8 positions, 2.54mm pitch, friction lock, tin plating, UL94 V-0.
