ILME CKSF03 naarasliitin 3P+PE jousivoimaliitin 10A 400V koko 21.21

Industrial connectors often fail when vibration loosens screw terminals or when cramped panels make wiring difficult. The ILME CKSF03 female insert solves both problems with spring-cage terminations that maintain constant contact pressure and allow tool-free wire insertion. It fits size 21.21 housings and provides a reliable 3-pole plus protective earth connection for 400 V circuits up to 10 A.
