At 2 width units and 70 mm installation depth, this RCBO fits standard distribution boards. That's wide enough for most indoor panel environments, including non-climate-controlled electrical rooms. The IP20 rating applies only when the distribution board is installed and conductors are connected — so don't leave it exposed during commissioning; the front face offers touch protection (finger-safe terminals per the product feature), but the back and sides rely on the enclosure.","metaTitle":"Siemens SENTRON 5SU1322-7KC40 RCBO, 40 A, 30 mA, C-curve, 50","metaDescription":"Siemens SENTRON 5SU1322-7KC40 RCBO, 2-pole, Type A, 30 mA residual current, C-curve 40 A, 50 kA breaking capacity per EN 60898. 2 width units, 70 mm deep.
