In this overview, the Hager ADM466C is compared with similar four-pole residual current circuit breakers with overcurrent protection (RCBO) from Siemens and CNC. All reviewed models serve the same primary purpose: protecting electrical circuits against overloads, short circuits, and earth leakage faults in residential and commercial electrical panels. Shared characteristics across most models include a four-pole configuration, 30mA Type A leakage sensitivity, and a 6kA breaking capacity. The key differences lie in the rated currents, tripping characteristics, and manufacturers.
⚙️ The table below compares key parameters such as the number of poles, rated current, tripping curve, residual current sensitivity, and breaking capacity, and provides a practical conclusion for each model.
| Parameter | Hager ADM466C | Siemens 5SU13466FP16 | CNC NV821921 | CNC NV821969 | CNC NV821945 | CNC NV821952 | Practical conclusion |
|---|
| Number of poles | 4 | 4 | 4 | 4 | 4 | 4 | All units are suitable for three-phase systems with neutral. |
| Rated current | 16A | 16A | 16A | 63A | 25A | 32A | The 16A models are designed for standard socket and lighting circuits, while 25A, 32A, and 63A versions suit heavier loads and supply lines. |
| Tripping curve | C | B | C | C | C | C | Curve C allows moderate inrush currents (for appliances), whereas Siemens Curve B reacts faster to overloads. |
| Residual current & type | 30mA, Type A | 30mA, Type A | 30mA | 30mA | 30mA | 30mA | All models provide fundamental personnel shock protection against earth leakage. |
| Breaking capacity | 6kA | 6kA | 6kA | 6kA | 6kA | 6kA | Identical short-circuit current withstand capability for standard distribution panels. |
◎ The table below evaluates the suitability of each model for different use cases and buyer profiles to help select the optimal solution.
| Use case | Recommended product | Why |
|---|
| Protecting standard group circuits with moderate inrush currents | Hager ADM466C or CNC NV821921 | The 16A rating and C-curve are optimal for typical household and office socket networks. |
| Circuits requiring faster overload protection response | Siemens 5SU13466FP16 | The B-curve provides quicker tripping during overcurrent events in sensitive circuits. |
| Safeguarding high-power lines or main distribution boards | CNC NV821969, CNC NV821945 or CNC NV821952 | Higher current ratings (25A, 32A, and 63A) accommodate heavier electrical loads and supply cabling. |
The Hager ADM466C differs from alternatives through its combination of a 16A rating, C-curve trip characteristic, and Type A sensitivity in a four-pole format, making it a well-rounded choice for standard three-phase loads and socket groups. Choose the Hager ADM466C if you need reliable circuit protection that accommodates typical equipment inrush currents. Consider Siemens if a B-curve is required, or the CNC models if you need alternative current ratings (25A, 32A, or 63A) for higher-capacity power lines.
