Mounting position is unrestricted — vertical, horizontal, upside-down — the thermal-magnetic trip works the same way. At 400 V AC, the breaker can switch off a fault of up to 10 kA — that's the short-circuit capacity per EN 60898. Pollution degree 2 means it expects only non-conductive dirt; in a dusty or humid environment, keep it inside a sealed enclosure. The 1.2 W power loss per pole at rated current is the heat it dumps into the panel — for a 2-pole breaker, that's 2.4 W total, negligible for most enclosures but worth noting if you're packing a dense row of breakers.","metaTitle":"Siemens 5SL4202-7CC SENTRON MCB, 2-pole C 2A 10kA","metaDescription":"Siemens 5SL4202-7CC SENTRON miniature circuit breaker, 2-pole, C-curve, 2A, 10kA interrupting capacity per EN 60898.

It shares the same 36 mm width, 76 mm depth, and DIN-rail mount, so it drops into the same panel footprint. The trade-off is lower fault-clearing capability; if your available fault current is under 6 kA, it's a direct fit without rewiring."},{"question":"What compliance documentation is available for 5SL4202-7CC?","answer":"The part carries EN 60898 certification for the 10 kA interrupting capacity. It is halogen-free and silicon-free, and designed for pollution degree 2 and overvoltage category III. RoHS and REACH compliance is standard for SENTRON products, but specific declarations are available on request."},{"question":"Where can I buy 5SL4202-7CC and how is it quoted?","answer":"We source and quote the 5SL4202-7CC to order against an RFQ.
