The Hager CEC463J is compared with a selection of similar four-pole residual current circuit breakers from Hager, Eaton, Schelinger, and Siemens. All presented devices are designed to protect electrical circuits against earth leakage faults and prevent electric hazards in residential, commercial, or industrial distribution boards. The primary differences between them lie in the rated current, residual operating current sensitivity, and protection type (AC or A), which determine the level of safety and application scope.
⚙️ Comparison of the technical characteristics of the reviewed device with alternative models across key parameters such as pole count, rated current, sensitivity, and protection type.
| Parameter | Hager CEC463J | Hager CFC440J | Eaton PFIM-63/4/003-A-MW | Hager CEC440J | Schelinger 70793 | Siemens 5SV43460KL | Practical significance |
|---|
| Pole count | 4-pole | 4-pole | 4-pole | 4-pole | 4-pole | 4-pole | All models are suitable for three-phase electrical systems with neutral. |
| Rated current | 63A | 40A | 63A | 40A | 63A | 63A | Determines maximum load capacity: 63A models support higher connected power. |
| Leakage current (sensitivity) | 0.1A (100mA) | 0.3A (300mA) | 30mA | 100mA | 30mA | 30mA | A lower threshold (30mA) provides direct contact protection, while 100mA and 300mA are typically used for fire protection. |
| Protection type | Type AC | Type AC | Type A | Type AC | Type AC | Type AC | Type A responds to both alternating and pulsating direct current, unlike Type AC. |
◎ Comparison of use cases and suitable operating conditions for each device to help choose the best option for specific requirements.
| Use case | Recommended product | Why |
|---|
| Protection of high-load three-phase lines with focus on fire safety | Hager CEC463J | Combines a 63A rated current with a 100mA sensitivity, optimal for main distribution boards. |
| Circuits with lower load and fire protection requirements | Hager CFC440J | Features a 40A rating and 300mA sensitivity for broader circuit protection. |
| Residential spaces with enhanced protection requirements against electric shock | Eaton PFIM-63/4/003-A-MW | Combines a 63A rating and high 30mA sensitivity of Type A for comprehensive safety. |
| Standard protection of moderate-power three-phase circuits | Hager CEC440J | Designed with a 40A rating and 100mA sensitivity for distribution boards. |
| General-purpose protection for modern wiring circuits | Schelinger 70793 | Provides essential 63A protection with a 30mA sensitivity to prevent electric shock. |
| Reliable protection for standard three-phase electrical installations | Siemens 5SV43460KL | Offers a combination of a 63A rating and Type AC 30mA sensitivity for standard tasks. |
The Hager CEC463J differs from alternatives through its combination of a 63A rated current and 100mA sensitivity (Type AC), making it a solid choice for distribution boards where higher-load lines need protection primarily against earth leakage and fire risks. If heightened personal protection against direct contact with a 30mA threshold is required, options with the same 63A rating but lower sensitivity thresholds from Eaton or Siemens would be more suitable.
