Product details

It mounts in any position — no derating needed for horizontal or inverted orientation.

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.

Frequently asked questions

How do I get current pricing and availability for 5SY4480-7CC?

Pricing and availability are confirmed at quote time against an RFQ. Submit a request through the storefront; the sourcing team will return current lead time and price for your quantity.

What is 5SY4480-7CC's breaking capacity at 400 V?

It is rated 10 kA at 400 V AC per IEC 60947-2. Under UL 1077 / CSA C22.2 No. 235, the rating is 5 kA.

What modular width does 5SY4480-7CC occupy?

It occupies 4 modular width units (72 mm wide) on a DIN rail. Depth is 76 mm, height 90 mm.

Will 5SY4480-7CC drop into a panel specified around 5SY4140-7 without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. The difference is the current rating — 5SY4480-7CC is 80 A C-curve, while 5SY4140-7 is a lower-current variant. No rewiring is needed if the busbar and cable are sized for 80 A.

What compliance documentation does Siemens provide for 5SY4480-7CC?

The breaker carries IEC 60947-2 ratings, UL 1077 and CSA C22.2 No. 235 certifications, and is halogen-free and silicon-free. Standard Siemens declarations of conformity (CE, UKCA) and RoHS/REACH documentation are available on request.
