The Siemens 5SL3502-7 is a SENTRON miniature circuit breaker rated 2 A with a C-curve trip characteristic, in a 1P+N (2-pole) configuration that switches both phase and neutral on a 230 V AC single-phase supply. It breaks faults at 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, covering residential and light commercial infrastructure panels.
The 2 A rating is the continuous current at 30 °C — derate to 1.9 A at 40 °C and 1.75 A at 55 °C (–), so a warm panel or high-ambient enclosure needs headroom. The 1P+N design switches the neutral pole along with the phase — required in many residential codes for single-phase final circuits so the neutral is not left floating when the breaker opens. The 2-module-width footprint on DIN rail matches standard panel layout; 36 mm wide and 76 mm deep with 70 mm installation depth. Breaking capacity of 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 is typical for residential distribution boards where the prospective short-circuit current stays below those levels. If your utility transformer is close or the service entrance has higher fault current, step up to a 6 kA or 10 kA rated breaker.
Deployment context
Snap-on DIN-rail mount (: any position), IP20 with connected conductors — intended for enclosed distribution boards, not open-panel washdown areas.
