It operates on 230/400 V AC supply at 50 Hz and uses an instantaneous (non-time-delayed) design, meaning it trips as soon as the residual current exceeds the threshold — no intentional delay for selectivity with downstream devices. That 10 mA sensitivity makes it suitable for circuits where a lower leakage threshold is required, such as circuits supplying socket outlets in certain residential or commercial applications, or where additional protection against direct contact is specified.
The 2-pole form factor fits standard DIN-rail enclosures, occupying a single modular width unit (roughly 18 mm per pole). The instantaneous design means it cannot be used as a selective (S-type) RCD for discrimination with downstream devices — if your distribution board requires time-delayed coordination, you would need a different variant.
