That 10 kA rating holds at 400 V AC — enough for most residential and light commercial distribution boards where the prospective fault current is under that threshold. The B-curve (3-5× In instantaneous trip) makes it a standard choice for resistive and general-purpose loads; it's not intended for motor-starting inrush, which would need a C or D curve. ## Panel fit and mounting The 5SL4210-6 occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is any, so it fits horizontal busbar arrangements without derating. IP20 with connected conductors — standard for enclosed distribution boards; no washdown rating, so keep it behind a gland plate or enclosure door. The sealable design allows the installer to lock the toggle position after commissioning. ## Environmental and compliance Halogen-free and silicon-free construction, rated for ambient temperatures from -40 °C to 75 °C. Pollution degree 2, overvoltage category III, energy limitation class 3. Suitable for residential buildings and infrastructure per the manufacturer's designation. Supplementary devices (auxiliary switches, shunt trips, etc.) can be installed on the side.","metaTitle":"Siemens 5SL4210-6 SENTRON MCB, 2P B 10A 10kA","metaDescription":"Siemens 5SL4210-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 10 A, 10 kA breaking capacity per EN 60898.

The 5SL4210-6 will not drop into a panel wired for the 5SL4363-7 without rewiring — different pole count, different current rating, and different trip curve. They share the same SENTRON family, depth, temperature range, and breaking capacity (10 kA)."},{"question":"What compliance documentation does Siemens provide for 5SL4210-6?","answer":"The 5SL4210-6 is certified to EN 60898 and IEC 60947-2 for breaking capacity. It is halogen-free and silicon-free. Standard Siemens documentation includes a declaration of conformity (CE), RoHS, and REACH compliance data — available on request with the order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4210-6","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/5SL4210-6 when reusing this data.
