It breaks fault currents up to 6 kA per EN 60898 at 230/400 V AC — the standard for residential and light commercial distribution boards. The C-curve (5–10× In) handles moderate inrush from small motors, pumps, and lighting ballasts without nuisance trips, while still clearing hard faults fast enough to protect downstream wiring. ## Fit and panel integration Single modular width (18 mm) snaps onto standard DIN rail. Depth of 76 mm and height of 90 mm keep it within the envelope of a typical consumer unit or sub-distribution board. Mounting position is unrestricted — install vertically, horizontally, or flat. The IP20 rating (with conductors connected) is standard for enclosed panels; no special sealing required. ## Environmental and compliance notes Halogen-free and silicon-free construction — relevant for panels in clean-room or high-reliability environments where outgassing must be minimized. Rated for ambient temperatures from -40 °C to 75 °C, covering most indoor and sheltered outdoor installations. Overvoltage category III and pollution degree 2 suit fixed-installation mains distribution.","metaTitle":"Siemens 5SL6120-7CC SENTRON MCB, 1P C 20A 6kA","metaDescription":"Siemens SENTRON 5SL6120-7CC miniature circuit breaker, 1-pole, C-curve, 20 A, 6 kA per EN 60898.
