SENTRON 5SU1324-7FA13 — RCBO, 2-pole, 13 A, C-curve, 30 mA
The Siemens 5SU1324-7FA13 is a SENTRON RCBO (residual current circuit breaker with overcurrent protection) — a combined device that packs both overcurrent and residual-current protection into one 3-module-width unit (54 mm wide, 77 mm deep, 90 mm tall). It is a 2-pole design (2P) protecting both poles against overcurrent and the circuit against earth faults. The residual-current element is Type A, tripping at 30 mA.
Above that, derate: 12.48 A at 40 °C, 12.22 A at 45 °C, 11.96 A at 50 °C, 11.57 A at 55 °C, 11.31 A at 60 °C, 10.53 A at 65 °C, and 10.01 A at 70 °C. If the distribution board runs warm, size the circuit for the derated current, not the nameplate 13 A. IP20 applies once the distribution board is installed with conductors connected.
