The Type B tripping characteristic means the magnetic release operates between 3 and 5 times the rated current, per EN 60898, so it suits predominantly resistive loads with modest inrush — lighting, small heaters, socket outlets in domestic or light commercial distribution boards. Rated 25 A at 30 °C ambient, the device derates to 23.5 A at 40 °C, 22.75 A at 45 °C, 21.75 A at 50 °C, and 20.25 A at 55 °C. The unit occupies a single 18 mm modular width on a DIN rail. The IP20 rating applies only when the distribution board is installed and conductors are connected — this is not a standalone outdoor device. Supply is brought in from below per the manufacturer's marking. Mounting position is any, so the RCBO can be oriented horizontally or vertically inside the enclosure without affecting the ratings. The 1P+N design switches and protects only the line conductor; the neutral is switched but not protected.","metaTitle":"5SU9306-6ES25 RCBO, Type B, 25 A, 6 kA, 1P+N","metaDescription":"Crabtree Starbreaker 5SU9306-6ES25 RCBO, 25 A rated at 30 °C, Type B trip curve, 6 kA breaking capacity per EN 60898. 1-module wide.
