Breaking capacity is 4.5 kA per EN 60898 for residential and commercial distribution boards, and 15 kA per IEC 60947-2 for industrial panel applications — the higher figure gives headroom for fault currents at the service entrance.
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.
