Neutral switching is included, so the neutral pole opens and closes with the phase, which is required in some regional wiring rules. Depth is 77 mm, height 90 mm, installation depth 70 mm. Touch protection is built in.","metaTitle":"Siemens SENTRON 5SU9353-1KK16 RCBO, 16A, 30mA, Type AC, 2-po","metaDescription":"Siemens SENTRON 5SU9353-1KK16 RCBO, 16 A rated, 30 mA residual, Type AC, 2-pole, 4.5 kA breaking capacity per EN 60898.
