Schneider Electric A9D32625 | Acti9 iDPN N Vigi 25A RCBO 1P+N C Curve | 6kA Type A
The Schneider Electric A9D32625 is a 25 A residual current breaker with overcurrent protection, from the Acti9 iDPN N Vigi range. It performs two protective functions at once. Overcurrent protection follows a C characteristic, comparable to an MCB, and earth-leakage protection operates at 30 mA Type A sensitivity, comparable to an RCD. The A9D32625 is a 1P+N device with a 6000 A breaking capacity.
Switchboards fill up fast. Every circuit wanting both overcurrent and earth-leakage protection is another call on rail space, and the A9D32625 delivers both across four 9 mm pitches, or 36 mm of rail. The 30 mA residual current stage operates instantaneously, with no intentional delay, and the sensing mechanism is voltage independent. A C characteristic gives motors and switch-mode equipment room to start, delaying magnetic operation until five to ten times the 25 A rating.
On the board it mounts to DIN rail by clip-on installation, and accepts a comb busbar at either the top or bottom connection. Terminals accommodate conductors to 16 mm2 rigid or 10 mm2 flexible, with a 15 mm stripping length and 2 N.m tightening torque specified at either connection. The toggle accepts a padlocking device for isolation, and local signalling indicates an ON, OFF or fault trip condition at a glance.
Features
- 25 A rated current — sized for a single-phase final subcircuit at 230 to 240 V AC, 50 Hz.
- C curve characteristic — magnetic operation sits between five and ten times rated current, so start-up surges do not nuisance trip it.
- 30 mA earth-leakage — operates instantaneously, with no intentional delay built into the residual current path.
- Type A class — the earth-leakage side is Type A, not Type AC.
- 6 kA breaking capacity — 6000 A Icn is the ceiling for the A9D32625, so check it against the prospective fault current at the board.
- Comb busbar — connects top or bottom, on the usual 9 mm phase to neutral pitch.
- Terminals to 16 mm2 — 1 to 16 mm2 rigid, or 1 to 10 mm2 flexible, top or bottom.
- Padlockable toggle — accepts a padlocking device for isolation, so the circuit stays dead while work is underway.
- IP20 as supplied — the A9D32625 reaches IP40 once it is sitting inside a modular enclosure.
Where to use
- Domestic final subcircuits — the A9D32625 covers 25 A power circuits on a single-phase supply.
- Light commercial boards — positioned on the outgoing side of a distribution board.
- Busbar-fed rows — the 9 mm pitch keeps a row of devices lining up on the comb.
- Boards needing lock-off — the padlock point lets the circuit be isolated and tagged before work starts.
- Single-phase supplies — rated for 230 to 240 V AC at 50 Hz.
A couple of things the A9D32625 is not: it is IP20 as supplied, so it belongs inside a distribution board or modular enclosure rather than out in the open. It is a 1P+N device, so it provides overcurrent and earth-leakage protection on one phase only, with no three-phase capability. And 6 kA is the ceiling, so verify it against the prospective fault current calculated at the board. Installation into a switchboard is licensed electrical work throughout Australia.
