The 30 mA sensitivity and type A residual current detection mean it catches sinusoidal AC faults and pulsating DC faults up to 6 mA smooth DC — the standard choice for circuits with single-phase rectifiers, switching power supplies, or variable-speed drives downstream. The short-time delayed characteristic (0.3–0.5 s typical) provides selectivity against instantaneous RCCBs upstream, so a downstream fault clears without tripping the main board's RCD.
Depth is 70 mm, matching the standard installation depth for SENTRON modular devices. IP20 protection applies only when the distribution board is installed with connected conductors.
