How to select a Schneider Electric Acti9 iC60 RCBO by pole count, current rating, tripping curve (B / C / D), residual-current sensitivity (10 / 30 / 100 / 300 mA), waveform class (AC / A / F / B) and short-circuit breaking capacity (Icn). Includes decoding of the Acti9 catalog reference A9D…, application map for residential vs. commercial vs. industrial installations, and cross-reference to comparable ABB DS201, Hager ADC and Siemens 5SU RCBO families.
An RCBO (Residual Current circuit Breaker with Overcurrent protection, IEC 61009-1) combines two protection functions in one modular device: overcurrent (thermal + magnetic release, like an MCB) and residual current (earth-leakage detection, like an RCD). The Schneider Electric Acti9 iC60 range implements this combination in the standard 18 mm modular width, so it drops directly into any DIN-rail consumer unit or distribution board.
Every Acti9 iC60 RCBO carries a nine-character reference of the form A9DxxxxNN. Each position encodes a selection parameter, so the reference alone tells the buyer exactly which protective device is fitted.
| Position | Encodes | Values |
|---|---|---|
| A9D | Product family | Fixed: Acti9 iC60 RCBO |
| char 4 | Curve + waveform class | 1 = C-curve type AC; 3 = C-curve type A; 4 = B-curve; 5 = D-curve; 7 = C-curve type F |
| char 5 | Sensitivity (IΔn) and Icn | 4 = 30 mA / 6 kA; 7 = 30 mA / 10 kA; 8 = 100 mA / 10 kA; 9 = 300 mA / 10 kA |
| chars 6-7 | Rated current In (A) | 06, 10, 13, 16, 20, 25, 32, 40 |
| chars 8-9 | Pole configuration | 15 = 1P+N (2 modules); 16 = 2P (2 modules); 35 = 3P+N (4 modules); 36 = 4P (4 modules) |
Character 4 = 7 (C-curve, type F). Character 5 = 2 (older 30 mA code). Chars 6-7 = 16 (rated 16 A). Chars 8-9 = 16 (2P). This resolves to a C-curve, type-F RCBO, 2-pole, 16 A, 30 mA sensitivity, 10 kA breaking capacity. Type-F is required on circuits fed by variable-speed drives (single-phase inverter output) because the residual current is a mixed DC + AC waveform that type-A cannot see reliably.
| IΔn | Function | Typical application |
|---|---|---|
| 10 mA | Additional shock protection | Medical wet-zone circuits, portable equipment in bathrooms |
| 30 mA | Personal-protection (life protection) | Domestic and small-commercial socket circuits, IEC 60364-4-41 mandatory |
| 100 mA | Fire and equipment protection | Fixed-load circuits, small industrial machinery |
| 300 mA | Fire protection only | Main incomer selectivity, industrial motor drives |
| 500 mA | Fire protection only | Selectivity above 300 mA sub-circuits |
Type AC senses sinusoidal residual current only. Type A additionally senses pulsating DC residual current. Type F extends type A with sensitivity to mixed-frequency (up to 1 kHz) residual current and short-duration DC pulses, and is mandatory on the load side of a single-phase VFD. Type B extends further to smooth DC residual current, and is required on the load side of a three-phase VFD or on EV charging equipment per IEC 62955.
