Type A residual-current detection catches both sinusoidal AC faults and pulsating DC fault currents — the standard requirement for single-phase electronics, variable-speed drives, and appliances with rectifier front ends. The 30 mA trip threshold provides supplementary protection against direct-contact shock in final circuits. ## Panel fit and installation Depth is 77 mm, installation depth 70 mm — confirm enclosure depth clearance, particularly in shallow consumer units or compact sub-distribution boards. Mounting position is unrestricted, and supply can enter from either top or bottom, which simplifies busbar routing. Mechanical endurance is 10,000 switching cycles typical.","metaTitle":"Siemens 5SU9353-7CN10 SENTRON RCBO, 10A C-Curve, 30mA Type A","metaDescription":"Siemens SENTRON 5SU9353-7CN10 RCBO, 1P+N, 10A, C-curve, 30mA Type A residual current, 4.5kA breaking capacity.

It shares the same 1P+N pole configuration, 2 MW width, and 4.5 kA breaking capacity, so it drops into the same DIN-rail footprint and busbar layout.
