The Siemens 5SY5163-7CC11 is a 1-pole C-curve miniature circuit breaker from the SENTRON series, rated 63 A at 220 V DC with a maximum DC voltage of 250 V. Its 10 kA DC breaking capacity per IEC 60947-2 means it can safely interrupt fault currents up to that level on a DC rail without cascading upstream — critical for DC auxiliary buses in traction or industrial DC distribution.

Frequently asked questions
Where can I buy 5SY5163-7CC11 and get a price?
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for this order code.
Will 5SY5163-7CC11 drop into a panel specified around 5SY3132-6?
The 5SY5163-7CC11 shares the same 18 mm width, 90 mm height, 76 mm depth, DIN-rail mounting, and SENTRON terminal layout as the 5SY3132-6. The key difference is DC-only rating (220 V DC / 250 V DC max) versus the 5SY3132-6's AC rating (400 V AC). If the panel feeds a DC auxiliary bus, it is a direct mechanical swap; if the original circuit was AC, the 5SY5163-7CC11 is not a functional substitute.
What compliance documentation does Siemens provide for 5SY5163-7CC11?
The breaker carries IEC 60947-2 certification for its 10 kA DC breaking capacity and is designed per railway standards. Overvoltage category III. The evidence does not list UL, CSA, RoHS, or REACH declarations — verify with the manufacturer or your Siemens channel partner for the specific compliance package.
