The ABB 1SDA055016R1 is a factory-crimped copper connection kit (FC CU) sized for a single 240 mm² conductor. It is a current-production accessory, so the supply chain is stable and the part is fully traceable through the authorized channel — no gray-market risk on this line.
What the kit contains and where it fits
This is a connection kit for ABB's SACE air circuit breaker range — specifically the FC CU variant for a 1x240 mm² copper cable. It includes the crimp lugs, insulating shrouds, and mounting hardware needed to terminate a single conductor per phase. The 240 mm² cross-section matches the typical cable size for a 630 A to 1600 A breaker frame, depending on the specific SACE model. Verify the breaker frame and terminal spacing against your panel layout before ordering; the kit is designed for a specific bolt-hole pattern and phase pitch.
