Snap-on DIN rail mount, any orientation. The 7-module width (126 mm) and 70 mm depth fit standard distribution board cutouts — verify gland plate clearance if retrofitting into a panel originally laid out for narrower single-function breakers. IP20 rating applies only with connected conductors in an installed distribution board — not rated for wet or dust-exposed locations. Rated for 50 Hz AC supply only, with insulation voltage of 440 V and surge voltage resistance of 4 kV.","metaTitle":"Siemens 5SU1344-7RC32 SENTRON RCBO, 32 A, 4P, C, 30 mA","metaDescription":"Siemens SENTRON 5SU1344-7RC32 RCBO, 32 A, 4-pole, C-curve, 30 mA Type A. 10 kA (EN 60898) / 15 kA (IEC 60947-2).
