The C-curve tripping characteristic (rated 10 A at 30 °C, per) means it holds up to 5–10× rated current for short overloads and trips magnetically on higher faults; it is sized for loads with moderate inrush, such as lighting banks, small motor circuits, or general socket outlets. The breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — adequate for most domestic and light commercial installations where the prospective short-circuit current stays under those thresholds. At 40 °C the continuous rating derates to 9.39 A, at 45 °C to 9 A, and at 55 °C to 8.4 A; if the panel ambient runs hot, factor the derating into the load schedule.
The 5SL3510-7 occupies 2 modular width units (36 mm,) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted. Touch protection is built in. The neutral conductor is switched internally, so no separate neutral-link breaker is needed for the protected circuit.
