The Siemens SENTRON 5SL6108-7 is a 1-pole miniature circuit breaker with a C tripping curve rated at 8 A. It breaks fault currents up to 6 kA under both EN 60898 and IEC 60947-2, which covers most residential and light commercial panelboards. The C-curve means it holds through motor inrush and transformer energization — trips between 5 and 10 times rated current — so it's a common choice for lighting, receptacle, and mixed-load branch circuits where the start-up surge isn't extreme. At 18 mm wide (one modular unit) and 76 mm deep, it snaps onto standard DIN rail and leaves room for auxiliary contacts or shunt trips on the same bus. The IP20 finger-safe terminals are live once conductors are connected, which is normal for this class — just keep the panel dead during swap-out.
Mounts in any position. Installation depth is 70 mm. Sealable. Rated for overvoltage category III and pollution degree 2, which covers fixed-wired distribution boards in dry, non-conductive environments. The -40 °C to 75 °C operating range means it lives in unheated utility rooms or outdoor enclosures without derating — one less thing to calculate on a cold morning startup.
