The C-curve means magnetic trip occurs at 5–10× In — suited for loads with moderate inrush, like lighting banks or small motor circuits. The 30 mA residual sensitivity provides supplementary protection against direct contact in TN or TT systems. The 4.5 kA breaking capacity per EN 60898 certifies it can interrupt a short-circuit fault up to that level; for installations with higher prospective fault current, a current-limiting upstream MCB or fuse is needed. The unit snaps onto a standard DIN rail (35 mm per EN 60715) and occupies 2 modular width units (36 mm total). Depth is 77 mm, installation depth 70 mm. Supply can enter from either top or bottom. Mounting position is any, which simplifies panel layout. No successor or phase-out notice is on record.","metaTitle":"Siemens 5SU9353-1KK63 SENTRON RCBO, 63A C-curve 30mA","metaDescription":"Siemens 5SU9353-1KK63 SENTRON RCBO, 63 A rated, C characteristic, 30 mA residual current, 4.5 kA breaking capacity.
