The Hager CDA240J is compared against several similar residual current circuit breakers (RCCBs), including the Hager CDA216J, Eaton PFIM-40/2/003-MW, Kanlux KRD10-2/40/30-A, Hager CDA225J, and Legrand 411555 DX3. All of these devices share the fundamental purpose of ensuring electrical safety and preventing electric shocks in residential and commercial buildings. The key differences among them lie in their rated current capacities, RCCB classification types (Type A versus Type AC), and brand manufacturers.
⚙️ The table below compares the core characteristics and differences, such as pole count, rated current, leakage current sensitivity, and the practical application of each device.
| Parameter | Hager CDA240J | Hager CDA216J | Eaton PFIM-40/2/003-MW | Kanlux KRD10-2/40/30-A | Hager CDA225J | Legrand 411555 DX3 | Practical significance |
|---|
| Pole count | 2P | 2P | 2P | 2P | 2P | 2P | All options are designed for standard single-phase electrical installations. |
| Rated current | 40A | 16A | 40A | 40A | 25A | 40A | Determines maximum load capacity: the Hager CDA240J supports higher-load electrical circuits compared to the 16A and 25A versions. |
| Sensitivity | 30mA | 30mA | 30mA | 30mA | 30mA | 30mA | All models provide the standard personal protection threshold against electric shock. |
| RCCB type | Type A | Type A | Type AC | Type A | Type A | Type A | The Eaton model is Type AC and only detects alternating currents, whereas the other options (Type A) also protect against pulsating direct currents, which are common in modern appliances. |
| Brand | Hager | Hager | EATON | Kanlux | Hager | Legrand | Different brands provide alternative options depending on brand preference or existing electrical panel compatibility. |
◎ The table below evaluates which product is more suitable for different user needs and practical application scenarios.
| Use case | Recommended product | Why |
|---|
| Protecting high-load circuit groups in homes or offices | Hager CDA240J | The 40A rating handles heavy electrical loads effectively, while Type A classification ensures broad fault detection. |
| Protecting low-load circuits or individual rooms | Hager CDA216J | The 16A rated current is optimal for lighter loads where high current capacity is unnecessary. |
| Circuits with basic resistive appliances without switching power supplies | Eaton PFIM-40/2/003-MW | Type AC is suitable for basic non-electronic loads, although it offers less versatility than Type A. |
| Alternative brand choices for Type A protection | Kanlux KRD10-2/40/30-A or Legrand 411555 DX3 | Deliver equivalent safety standards and Type A functionality from alternative manufacturers. |
The Hager CDA240J differs from alternative models by offering a robust 40A current capacity combined with Type A protection, making it ideally suited for safeguarding heavily loaded circuits in residential or commercial settings utilizing modern electronics. Choose this model when you need a dependable, high-capacity safety switch capable of handling both alternating and pulsating residual currents.
