Description

Screw connection plugs in three pitches

The 15K range provides single-row pluggable terminal blocks with screw wire termination. Choose the pitch, mating profile, pole count and fixing arrangement together. K, KA, KB and KC profiles have different outlines; M versions add fixing flanges. Match the complete outline to the intended header rather than selecting by pitch alone.
