The Siemens SENTRON 5SU1354-6LB32 is a 2-pole (1P+N) RCBO combining a B-curve miniature circuit breaker with Type A residual current protection, rated 32 A at 30 °C. The short-time delayed G characteristic (super resistant K) means it tolerates brief inrush without nuisance tripping, useful on motor or capacitive loads.
DIN-rail footprint and temperature derating
Supply cord position can be either top or bottom, and mounting position is unrestricted — no orientation constraints in the panel. Rated current derates with ambient temperature: 32 A at 30 °C, 30.4 A at 40 °C, 29.76 A at 45 °C, 28.8 A at 50 °C, 27.84 A at 55 °C, 27.2 A at 60 °C, 25.92 A at 65 °C, and 24.64 A at 70 °C.
Construction and compliance
Halogen-free and silicon-free construction, so it meets clean-room and semiconductor-fab material restrictions.
