This is a DC-specific MCB — the 440 V DC maximum rating means it can handle series strings common in solar combiner boxes, UPS battery banks, and DC bus distribution, where standard AC-rated MCBs would fail to interrupt a DC arc. The 2-pole design switches both lines simultaneously, which is necessary for ungrounded DC systems to ensure full isolation on a fault. The IP20 rating applies with conductors connected, so it's intended for protected panel or enclosure installation, not open wet locations. The 90 mm height is standard for SENTRON 5SL breakers — drops into existing 5SL panel layouts without re-spacing. Mounts in any position, which simplifies layout in tight enclosures where vertical rail orientation is needed.","metaTitle":"Siemens 5SL5202-7RC SENTRON MCB, 2-pole DC, 440 V, 10 kA, C-","metaDescription":"Siemens 5SL5202-7RC SENTRON miniature circuit breaker, 2-pole, 440 V DC, 10 kA breaking capacity, C-curve.

The C-curve trips between 5x and 10x rated current, suited for moderate inrush loads like small DC motors, contactor coils, or capacitor banks."},{"question":"Will the 5SL5202-7RC fit in a panel designed for the 5SL6220-7?","answer":"Yes — both share identical dimensions: 36 mm width (2 MW), 76 mm depth, 90 mm height, and 70 mm installation depth. The 5SL5202-7RC will drop into the same DIN-rail slot and panel cutout without any rewiring of the bus bar or enclosure modification."},{"question":"Where can I buy the 5SL5202-7RC and how is it quoted?","answer":"We source and quote this part to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for your target quantity and delivery window."},{"question":"What compliance documentation is available for the 5SL5202-7RC?","answer":"As a Siemens SENTRON product, it carries the expected CE marking for the European market. The housing is halogen-free and silicon-free, meeting material compliance requirements for clean environments.
