The Hager CEC440J 4-pole residual current circuit breaker 40A 100mA type AC is compared with several alternative four-pole residual current circuit breakers from Hager, Noark, and EATON. All reviewed models are designed for electrical safety, protecting installations against earth leakage currents and electric shock in residential, commercial, and industrial distribution boards. The primary differences lie in their rated current, residual operating current sensitivity, tripping type (AC, A, or F), and breaking capacity.
⚙️ The table below compares key characteristics such as the number of poles, rated current, sensitivity, device type, and breaking capacity.
| Parameter | Hager CEC440J | Hager CFC440J | Hager CDF640D | Noark 8472 | EATON PFIM-40/4/003-A-MW | Hager CEC463J | Practical significance |
|---|
| Poles | 4-pole | 4-pole | 4-pole | 4-pole | 4-pole | 4-pole | All models are suitable for three-phase networks with a neutral wire. |
| Rated current | 40A | 40A | 40A | 63A | 40A | 63A | 40A models are designed for standard distribution lines, whereas 63A units handle higher total load currents. |
| Sensitivity | 100mA | 300mA | 300mA | 100mA | 300mA | 100mA | 30mA provides basic protection against direct contact, while 100mA and 300mA are typically used for fire protection or equipment safety. |
| Type | Type AC | Type AC | Type F | Type A | Type A | Type AC | Type AC responds to sinusoidal alternating current, whereas Types A and F also provide protection against pulsating direct current and complex electronic loads. |
◎ The table below evaluates which product is more suitable for various use cases and load types.
| Use case | Recommended product | Why |
|---|
| Standard protection for AC circuits with 100mA leakage threshold | Hager CEC440J | Ideal for general distribution boards requiring 100mA sensitivity and Type AC protection in a four-pole 40A network. |
| Fire protection with a higher 300mA threshold | Hager CFC440J | Provides a matching 40A rating with a higher 300mA setting to prevent nuisance tripping in larger or branched networks. |
| Circuits with frequency converters and complex electronics | Hager CDF640D | Features Type F protection and a 10kA breaking capacity, effectively securing modern lines with electronic loads. |
| Heavy-duty lines up to 63A with Type A protection | Noark 8472 | Offers a higher 63A rated current and Type A protection for detecting pulsating DC residual currents. |
| Standard protection against direct contact with 30mA | EATON PFIM-40/4/003-A-MW | Optimized for residential socket groups where enhanced 30mA sensitivity and Type A are required. |
| Distribution boards up to 63A with 100mA sensitivity | Hager CEC463J | Similar to the base model in Type AC and 100mA setting, but engineered for a higher 63A current rating. |
Choosing the Hager CEC440J 4-pole residual current circuit breaker 40A 100mA type AC depends on your specific electrical network requirements: opt for this model if you need a reliable four-pole, 40A solution with a 100mA threshold for standard AC setups, whereas circuits with complex electronics benefit more from Type A or F devices, and higher load lines require 63A options.
