The D characteristic means it tolerates the inrush of motor-driven loads (pumps, small conveyors, lifts) without nuisance tripping, while the type A residual-current element detects pulsating DC fault currents that a basic AC type would miss — essential on circuits feeding single-phase rectified loads like switching power supplies or VFDs. The 1+N pole configuration switches the phase and switches the neutral, but does not break the neutral on overcurrent — it opens the neutral only on residual fault. That is standard for single-phase RCBOs in many markets, but if your local code requires full neutral isolation on overcurrent, confirm before wiring. The Construction line shares the same module width as other 1+N RCBOs in the Siemens 5SU series — no special busbar or adapter needed. Wire termination is screw-clamp; strip length and torque follow the printed markings on the device side. The D characteristic curve and type A residual-current module are factory-sealed — no field adjustment.","metaTitle":"5SU9356-8CN16 RCBO 1+N 6 kA D char. type A, 16 A","metaDescription":"5SU9356-8CN16 RCBO, 1+N, 6 kA breaking capacity, D characteristic, type A, 16 A.
