What the ratings mean for fit
The 5SL6410-7RC is a Siemens SENTRON 4-pole miniature circuit breaker rated 10 A with a C tripping characteristic and a 7.5 kA breaking capacity per EN 60898 at 415 V AC. The C curve means it trips between 5 and 10 times the rated current — standard for inductive loads like small motors, fluorescent lighting banks, and transformer primaries where inrush exceeds a B-curve's tolerance. The 7.5 kA rating tells you it can safely interrupt a fault current up to that level at 415 V without welding contacts or cascading upstream; if your prospective short-circuit current at the panel exceeds that, you need a current-limiting upstream device or a higher-rated breaker. Four poles let it switch all three phases plus neutral in a single module — common for three-phase final subcircuits in commercial and light industrial distribution boards.
Panel integration and environment
Mounts on standard DIN rail in any position — no derating for upside-down installation. The 72 mm width (4 modular units) means it occupies four 18 mm slots in a distribution board; check your rail fill before committing. Depth of 76 mm and installation depth of 70 mm leave room behind the busbar stack. Rated IP20 with connected conductors — fine inside a closed panel but not for wet or dusty environments. The wide ambient range from -40 °C to 75 °C covers unheated enclosures in cold climates and hot switchrooms near transformers. Overvoltage category III and pollution degree 2 suit fixed installations downstream of the main distribution board.
Compliance and documentation
Rated per EN 60898 for the 7.5 kA breaking capacity. The SENTRON series carries CE marking and is designed for residential and infrastructure operation per the manufacturer's designation. Halogen-free and silicon-free construction — relevant for installations where outgassing during a fault must be minimized (e.g., occupied spaces, sensitive electronics nearby). Sealable design allows the installer to lock the toggle position after commissioning.
