Product details

DIN-rail footprint and panel integration

Single modular width unit at 18 mm, depth 76 mm, height 90 mm. Occupies one position on a standard DIN rail. Installation depth of 70 mm leaves clearance behind the rail for wiring. Accepts solid conductors up to 25 mm² — sufficient for a 50 A feed. Mounting position is unrestricted; the breaker can be oriented any way in the enclosure without derating.

Halogen-free and silicon-free construction. Overvoltage category III, pollution degree 2 — standard for fixed-installation distribution boards.

Frequently asked questions

Where can I buy 5SN4150-6CN and how do I get a price?

The part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the width of 5SN4150-6CN?

18 mm, which is one modular width unit on a standard DIN rail.

What compliance documentation does Siemens provide for 5SN4150-6CN?

The breaker carries EN 60898 certification for breaking capacity. It is halogen-free and silicon-free. For RoHS, REACH, and UL documentation, refer to the manufacturer's declaration package — the evidence does not list those specific certs on this variant.
