Type AC residual current detection means this RCBO responds to sinusoidal AC fault currents only — suitable for general-purpose circuits feeding resistive, inductive, and electronic loads where no pulsed DC fault signature is expected. The 30 mA trip threshold provides supplementary protection against electric shock per IEC 60364, covering most socket-outlet and lighting circuits in residential and light commercial installations. Rated insulation voltage (Ui) of 440 V and overvoltage category III confirm this RCBO is rated for fixed-installation distribution boards where transient overvoltages up to 4 kV (surge voltage resistance) are expected. The 50 Hz operating frequency matches standard mains supplies across Europe and Asia. Supply can enter from either top or bottom, and the neutral conductor is switched internally (no separate neutral bar required downstream). Touch protection is integrated on the terminals.","metaTitle":"Siemens 5SU1323-1BB10 SENTRON RCBO, 10 A, 30 mA, Type AC, C-","metaDescription":"Siemens SENTRON 5SU1323-1BB10 RCBO, 2-pole, 10 A, 30 mA Type AC, C-curve, 4.5 kA (EN 60898).

If your panel requires separate RCD and MCB, the 5SY plus a separate RCD block is the alternative; if you need the combined RCBO footprint, the 5SU is the direct fit."},{"question":"Where can I buy 5SU1323-1BB10?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
