Below that fault level, the breaker clears without upstream devices needing to trip — useful for coordinating a sub-panel fed from a larger MCCB. Under UL 1077 and CSA C22.2 No. 235, the rating drops to 5 kA, so verify the applicable standard for your jurisdiction. ## Panel integration checklist Combined terminal at both top and bottom accepts busbar or cable. Installation depth is 70 mm, leaving 6 mm clearance behind the 76 mm overall depth for wiring. Sealable — the toggle can be locked in the OFF position for LOTO compliance. Halogen-free and silicon-free construction, suitable for clean-room or food-processing environments where outgassing is restricted.","metaTitle":"Siemens 5SY4480-7CC SENTRON MCB, 4P C-Curve 80A 10kA, 400V A","metaDescription":"Siemens SENTRON 5SY4480-7CC miniature circuit breaker, 4-pole, C-curve, 80 A, 10 kA breaking capacity per IEC 60947-2 at 400 V AC.
