It is designed for DC circuits up to 125 V with a breaking capacity of 10 kA — so it handles fault currents from battery banks, DC bus lines, or solar combiner boxes without cascading upstream. The B-curve (3-5 In) means it trips fast on moderate overloads, making it a fit for resistive or lightly inductive DC loads where inrush is low. It snaps onto a standard DIN rail and occupies 1 modular width unit (18 mm), so it fits tight panel layouts. ## Physical fit and panel integration The 5SL5102-6CC measures 18 mm wide, 90 mm high, and 76 mm deep — standard SENTRON 5SL form factor. Installation depth is 70 mm behind the panel face. Mounting position is any orientation. IP20 with connected conductors, so it lives inside a closed panel or distribution board. The housing is halogen-free and silicon-free, which matters for environments sensitive to outgassing (clean rooms, medical, food processing). ## Key ratings and what they mean for your circuit Rated DC voltage 72 V maximum per pole, but the description states 125 V DC — that is the voltage at which the 10 kA breaking capacity is certified. The B-curve characteristic (tripping between 3 and 5 times rated current) means a 2 A breaker will hold steady-state loads up to 2 A and trip between 6 A and 10 A. Overvoltage category III and pollution degree 2 confirm it is rated for fixed-installation distribution boards (not just final circuits). Touch protection is built in, and the unit is sealable for tamper-proof metering or rental applications.","metaTitle":"Siemens 5SL5102-6CC SENTRON MCB, 1P B2, 125 VDC, 10 kA","metaDescription":"Siemens 5SL5102-6CC SENTRON miniature circuit breaker, 1-pole, B-curve, 2 A, rated 125 VDC at 10 kA.

The 5SL6132-6MB is an AC-rated 32 A B-curve unit (6 kA at 400 V AC), while the 5SL5102-6CC is a DC-rated 2 A B-curve unit (10 kA at 125 V DC). The physical footprint is identical, so a swap requires no panel rework — just verify the circuit voltage and load current match the new breaker's rating."},{"question":"What compliance documentation does Siemens provide for 5SL5102-6CC?","answer":"The product carries RoHS and halogen-free compliance by design. Full declarations (CE, UKCA, EAC) are available through the Siemens Industry Online Support portal. The part is not UL-listed (it is IEC/EN 60898 rated), so verify local code acceptance for DC distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL5102-6CC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SL5102-6CC when reusing this data.
