The 50 A rating is the continuous current at 30 °C ambient; at 40 °C it derates to 47 A, at 45 °C to 45.5 A, at 50 °C to 43.5 A, and at 55 °C to 40.5 A. The Type A fault current detection (30 mA typical for this class) handles residual currents from electronic loads that a simple AC type would miss. Combined with the C characteristic (magnetic trip at 5–10× In), it is suited for circuits with motor inrush or capacitive loads that would nuisance-trip a B curve. Power dissipation is 1.5 W maximum, which matters for thermal budgeting in a densely populated enclosure. The unit is halogen-free and silicon-free, a requirement in some clean-room or corrosive-environment specifications. Snap-on mounting to DIN rail EN 60715, 36 mm width (2 MW), 90 mm height, 77 mm depth (70 mm installation depth). IP20 rated when installed in a distribution board with connected conductors. Overvoltage category III, pollution degree 2 typical for fixed-installation switchgear. The unit is touch-protected per the product feature.","metaTitle":"Siemens 5SU9356-7KN50 SENTRON RCBO, 50 A, Type A, 30 mA, 6 k","metaDescription":"Siemens SENTRON 5SU9356-7KN50 RCBO, 50 A rated, Type A fault current, 30 mA sensitivity, 6 kA breaking capacity per EN 60898.
