Product details

The 5SN series is a current-production line, so this order code is an active BOM line item, not an obsolete cross-reference.

The 6 kA rating is the lower bound for residential/commercial duty; in an industrial panel, plan on the 15 kA number for coordination studies.

Voltage and conductor specs

On the DC side it's rated up to 72 V. The terminals accept solid conductors up to 35 mm², which is generous for a 2-pole breaker — it handles the larger wire sizes you'd see on feeder circuits or sub-distribution. Power loss per pole is 2.2 W in hot operating state at rated current, so thermal derating inside a crowded enclosure is worth checking if you're packing multiple units side by side.

This is a current-production Siemens SENTRON MCB, sourced through independent distribution channels. For BOM-freeze or tender submissions, the 5SN6225-7CP is a standard catalog item with no special lead-time flags — quote to order.

Frequently asked questions

Where can I buy 5SN6225-7CP and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is 5SN6225-7CP's listed depth (76 mm) on this component line?

The overall depth is 76 mm, with an installation depth of 70 mm. That 6 mm difference accounts for the front of the breaker protruding past the DIN rail.

What is 5SN6225-7CP's listed width (36 mm) on this component line?

Width is 36 mm, which corresponds to 2 modular width units (MWUs) on a standard DIN-rail panel. Each MWU is 18 mm.

Will 5SN6225-7CP drop into a panel that was specified around 5SU9354-7KK16 without rewiring?

Mechanically yes — both are 2-pole, 36 mm wide, 70 mm installation depth on DIN rail. But the 5SU9354-7KK16 is an RCBO (RCD + MCB combined), while the 5SN6225-7CP is a plain MCB. You lose the residual-current protection unless you add a separate RCD module. Also the 5SN6225-7CP has a higher IEC 60947-2 breaking capacity (15 kA vs 10 kA), so the SCCR coordination may need rechecking.
