The Siemens SENTRON 5SU1654-7KK32 is a 2-pole (1P+N) residual current circuit breaker with overcurrent protection — an RCBO that combines a 32 A rated thermal-magnetic trip (C-curve) with Type A residual current detection in a single 36 mm-wide module. The instantaneous design means magnetic trip acts fast on short-circuit; no intentional delay.
Power supply can enter from either top or bottom — no forced orientation. Mounting position is any, which helps when panel layouts are tight.
Temperature range spans -40 °C to 75 °C storage/operating, with derated current values above 30 °C: at 40 °C it's 30.4 A, at 50 °C it's 28.8 A, at 70 °C it's 24.64 A.
