The Type A classification means it detects both sinusoidal AC residual currents and pulsating DC residual currents — the standard for circuits feeding single-phase electronics, switch-mode power supplies, or appliances with rectifier stages.
The C-curve (magnetic trip between 5× and 10× In) suits motor-starter circuits, small transformers, or lighting banks with moderate inrush — the 32 A rating handles a 7.3 kW resistive load at 230 V or a 5.5 kW motor with appropriate coordination. The 30 mA residual sensitivity provides supplementary protection against direct contact in final circuits, as required by IEC 60364 for socket-outlet circuits and portable equipment.
In industrial panels with higher fault levels, upstream fusing or a higher-rated MCB is needed to keep the RCBO within its rated breaking capacity.
