The 5SV3111-6: The 10 mA sensitivity on a Type A RCCB means this unit detects sinusoidal AC residual currents plus pulsating DC residuals — common in modern electronics, variable-speed drives, and switched-mode power supplies. It is instantaneous (no short-time delay), so it trips on the first half-cycle of a fault, which is appropriate for circuits where nuisance tripping from transient surges is not expected. The 10 kA short-circuit current rating (SCCR) is the maximum prospective fault current the device can safely interrupt under IEC 60898-1. The device also carries a 0.5 kA rating according to IEC 61008-1, which governs the RCCB's performance under specific test conditions. For a main RCCB that sees infrequent operation, this is more than adequate; for a frequently switched load, consider the electrical life (not stated here) which is usually lower.
Depth is 70 mm, installation depth matches at 70 mm, height is 90 mm. Mounts in any position, supply can enter from top or bottom. The IP20 rating applies only when the distribution board is installed and conductors are connected — bare terminals are not finger-safe. Silicon-free construction, which matters for applications like automotive paint shops or semiconductor fabs where silicone outgassing can cause adhesion or contamination issues.
