The Siemens SENTRON 5SL5106-7RC is a 1-pole miniature circuit breaker rated 6 A with a C tripping characteristic, designed specifically for 220 V DC circuits and a breaking capacity of 10 kA per the description. This is a DC-only device — the operating voltage type is DC, and the maximum DC rated value is 220 V, so it is not a general-purpose AC/DC unit.
DC rating and what it means for fit
The 220 V DC maximum rating is the key selection parameter here. Unlike AC breakers that can handle a range of AC voltages, this unit's voltage type is explicitly DC. The C-curve characteristic means the magnetic trip operates at 5 to 10 times rated current — 30 to 60 A for this 6 A unit — which is standard for protecting inductive loads like contactor coils, relays, and small DC power supplies where inrush is moderate. The 1-pole design switches the single DC line; no neutral pole is included.
Panel integration and environment
The overvoltage category is III (fixed installation with transient overvoltage protection), and the degree of pollution is 2 (non-conductive pollution only).
