The Siemens SENTRON 5SM3314-6KL01 is a 2-pole residual current circuit breaker (RCCB) rated 40 A at 230 V AC, with a 30 mA trip threshold and Type A fault current sensitivity. It is short-time delayed, meaning it tolerates brief surge currents (rated 3 kA) without nuisance tripping — useful on circuits with inrush from switched-mode supplies or motor drives where a standard instantaneous RCCB would drop out.
The N-left configuration means the neutral terminal is on the left side of the device — verify orientation against your panel layout before wiring. Installation depth matches the 70 mm dimension; any mounting position is permitted.
Tightening torque range is 2.5 to 3 N·m.
Overvoltage category III, pollution degree for standard distribution board environment. Silicon-free construction is confirmed.
