It is designed for final circuits in residential and commercial distribution boards where both overload/short-circuit and earth-fault protection are required in one device. Rated 16 A at 30 °C ambient, it derates to 15.04 A at 40 °C, 14.56 A at 45 °C, 13.92 A at 50 °C, and 12.96 A at 55 °C — the thermal curve matters if the panel runs hot. The 30 mA residual trip covers personnel protection (indirect contact) and fire prevention. At 18 mm width (1 MW), it occupies one module position. Depth is 77 mm; installation depth 70 mm. Touch protection is built in (fingertip-safe terminals).","metaTitle":"Siemens 5SU9306-1KK16 SENTRON RCBO, 16A C-curve 30mA 6kA","metaDescription":"Siemens 5SU9306-1KK16 SENTRON RCBO, 2-pole, 16A rated, C-curve, 30mA residual current, 6kA breaking capacity.
