The Siemens 5SV9316-1CN16 is a 2-pole (1P+N) RCD-operated circuit breaker from the SENTRON 5SV9 series, combining overcurrent and residual current protection in a single 18 mm wide unit. The breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, so it safely clears faults up to that level in a 230/240 V AC circuit. The instantaneous design (no intentional delay) trips on residual current without time grading.
Current derating across temperature
At 40 °C it derates to 15.2 A, at 45 °C to 14.72 A, at 50 °C to 14.24 A, and at 55 °C to 13.76 A.
Occupies 1 width unit (18 mm) on a DIN rail. Depth is 77 mm, installation depth 70 mm, height 90 mm.
