The 4-wall shrouding protects the square male pins from accidental bending during handling and mating. The friction lock fastening type holds the mating receptacle in place without a secondary latch — enough for moderate vibration in an industrial cabinet or lighting fixture, but not a high-shock environment that calls for a positive locking ramp. Current rating varies by wire gauge — the crimp terminal and wire size determine ampacity. The 250VAC voltage rating and UL94 V-2 flammability cover lighting ballasts, small appliances, and general-purpose industrial control panels.","metaTitle":"1744427-4 TE Connectivity Header 4 Pos 3.96mm Economy Power","metaDescription":"1744427-4 TE Connectivity AMP Economy Power header, 4 circuits, 0.156\" pitch, shrouded, friction lock.
