The Siemens SENTRON 5SL4610-7 is a 4-pole miniature circuit breaker (3P+N) with a C-curve trip characteristic, rated at 10 A and 400 V AC. It provides a 10 kA breaking capacity under both EN 60898 and IEC 60947-2, which means it can safely interrupt fault currents up to that level in residential and infrastructure distribution boards. The 4-module-width (72 mm) body snaps onto standard DIN rail and accepts supplementary devices like shunt trips or auxiliary contacts.
What the ratings mean for fit
The 10 kA breaking capacity is the headline number for this class — it tells you the MCB can clear a bolted fault on a 400 V supply without welding its contacts or rupturing the case. That matches typical domestic and light commercial service-entrance requirements where the prospective short-circuit current stays under 10 kA. The C-curve trips between 5 and 10 times rated current, so it's sized for inductive loads like small motors, fluorescent lighting banks, or transformer inrush — not for pure resistive heaters (B-curve territory) or heavy motor starts (D-curve). The 4-pole 3P+N design switches all three phases and the neutral, with the neutral pole switching but not protecting — standard for TN or TT systems where you need a switched neutral for isolation. The 72 V DC maximum rating is a secondary capability for control circuits, not the primary application. Power loss per pole is 0.9 W at rated current in hot operating state. For a 4-pole breaker at full load that's 3.6 W total dissipated inside the enclosure — negligible in a ventilated board, but worth noting if you're packing multiple breakers into a sealed, thermally constrained panel.
Panel integration and compliance
Mounts on DIN rail in any position. The 72 mm width occupies 4 modular units. Installation depth behind the panel face is 70 mm, overall depth 76 mm. IP20 with connected conductors — protected against finger contact but not against moisture, so it belongs inside a distribution board, not in a washdown zone. Overvoltage category III and pollution degree 2 confirm it's rated for fixed-installation mains supply. Halogen-free and silicon-free construction — relevant for environments where outgassing from a fault could damage sensitive electronics or where silicone contamination must be avoided. Sealable for lockout/tagout compliance. Mechanical service life is 10,000 operating cycles typical.
