The 5SL6103-7CC: The C-curve (tripping characteristic class C) means the breaker trips at 5 to 10 times rated current — designed for moderate inrush loads like small motors, transformers, or lighting banks. At 3 A rated (30 °C ambient), the breaker carries 2.83 A at 40 °C, 2.74 A at 45 °C, 2.65 A at 50 °C, and 2.55 A at 55 °C — so if your panel runs warm, you must derate. The 6 kA breaking capacity (per EN 60898) is the maximum fault current it can safely interrupt at 400 V AC; this is suitable for residential and light commercial distribution boards, not high-fault industrial mains. The 1-pole design switches only the line conductor; neutral must be handled separately. Rated for AC only (400 V phase-to-phase max, 250 V phase-to-neutral), with a DC rating up to 72 V — useful for control circuits but not for high-voltage DC rails.
Deployment context
Snaps onto a standard 35 mm DIN rail (EN 60715) and occupies one 18 mm module. The IP20 rating with connected conductors means it is protected against solid objects larger than 12.5 mm but not against moisture — keep it inside a dry enclosure.
