Product details

Panel fit and mounting

Occupies 2 modular width units (36 mm) on a DIN rail. Depth is 76 mm, installation depth 70 mm — fits standard distribution boards and sub-panels. The quick assembly system snaps onto the rail without tools. Mounting position any, so vertical or horizontal rail orientation is fine. Combined terminals top and bottom accept copper conductors; touch protection is integral. Sealable, halogen-free, silicon-free — relevant for clean-room or food-bev environments where outgassing must be controlled.

Frequently asked questions

What is the DC breaking capacity of 5SY5220-7CC11?

10 kA at 440 V DC per IEC 60947-2. That is the maximum fault current it can safely interrupt at that voltage.

Will 5SY5220-7CC11 drop into a panel specified around 5SY4113-7CV without rewiring?

Both are 2-pole SENTRON MCBs on the same DIN-rail footprint (2 modular width units), so the mechanical fit is identical. The 5SY5220-7CC11 is rated 20 A C-char DC, while the 5SY4113-7CV is a lower-current variant — verify the load current and trip characteristic match before swapping.

Where can I buy 5SY5220-7CC11 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here.
