It's built for 230/400 V AC residential and infrastructure branch circuits where the load is modest but the short-circuit fault current could hit that 4.5 kA ceiling. The C-curve means it holds through inrush up to 5–10× rated current before tripping magnetically, so it's a fit for small motorized loads or lighting ballasts that draw a brief start surge. The IP20 rating (with conductors connected) is typical for enclosed distribution boards; finger-safe touch protection is built in. Halogen-free and silicon-free construction means it won't off-gas corrosive compounds in a sealed enclosure, which matters for sensitive electronics sharing the same cabinet. Rated for single-phase operation up to 250 V AC and multi-phase up to 440 V AC. The DC rating tops out at 72 V, so it's usable on low-voltage DC control circuits within that limit.","metaTitle":"Siemens 5SL3105-7MB SENTRON MCB, 1P C 0.5A 4.5kA","metaDescription":"Siemens 5SL3105-7MB SENTRON miniature circuit breaker, 1-pole, C-curve, 0.5 A, 4.5 kA breaking capacity per EN 60898.

The difference is the current rating (0.5 A vs 16 A) and the tripping curve (C vs B). It will physically install in the same panel position, but the circuit protection values are completely different — verify the load and coordination study before swapping."},{"question":"What compliance documentation does Siemens provide for 5SL3105-7MB?","answer":"The 5SL3105-7MB is built halogen-free and silicon-free, and carries an IP20 protection rating with connected conductors. It is designed to EN 60898 for breaking capacity and is part of the SENTRON family. Standard Siemens documentation includes the declaration of conformity for the Low Voltage Directive; specific RoHS and REACH declarations are available from Siemens upon request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL3105-7MB","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/5SL3105-7MB when reusing this data.
