The Hager MM504N is compared against alternative protective devices: Hager HTN363E, Eaton PKE12, Eaton 189906, Siemens 3RV2031-4EA10, and Hager HTS350E. All evaluated products are 3-pole electrical devices, but they differ significantly in their intended purpose, supported current ratings, and power capacity.
⚙️ Below is a comparison of characteristics such as device type, number of poles, operating voltage range, current rating, supported power, and practical application for different electrical loads.
| Parameter | Hager MM504N | Hager HTN363E | Eaton PKE12 | Eaton 189906 | Siemens 3RV2031-4EA10 | Hager HTS350E | Practical Conclusion |
|---|
| Device Type | Motor protection circuit breaker | 3-pole circuit breaker | Motor protective circuit breaker | Motor protection circuit breaker | Motor circuit breaker | 3-pole circuit breaker | Hager MM504N, Eaton PKE12, Eaton 189906, and Siemens 3RV2031-4EA10 are specifically designed for motor protection, whereas Hager HTN363E and HTS350E are built for power distribution networks. |
| Number of Poles | 3 | 3 | 3 | 3 | 3 | 3 | All compared devices support three-pole connections for three-phase systems. |
| Current Range | 0.4 - 0.63 A | 63 A | Up to 12 A | 16 - 20 A | 22 - 32 A | 50 A | Hager MM504N is tailored for very low-current electric motors, while the other alternatives suit higher-load equipment and distribution lines. |
| Power Rating | 0.18 kW | Not specified | Not specified | 9 kW | 15 kW | Not specified | Hager MM504N fits compact low-power motors, whereas heavy-duty industrial options from Eaton and Siemens handle demanding loads. |
| Voltage | 230 - 690 V | 230 / 400 V | 690 V | Not specified | Not specified | 230 - 400 V | Most devices support standard industrial voltages up to 690 V or standard 230/400 V networks. |
◎ The table below evaluates how well each product matches specific use cases and user needs to help you choose the right equipment for your installation.
| Use Case | Recommended Product | Why |
|---|
| Low-power electric motor protection | Hager MM504N | The precise 0.4-0.63A range and 0.18kW rating are optimal for small motors. |
| Commercial or residential power distribution | Hager HTN363E or Hager HTS350E | Designed for higher currents (63A and 50A) for power distribution rather than motor starting. |
| Medium and high-power industrial motor control | Eaton PKE12, Eaton 189906, or Siemens 3RV2031-4EA10 | Support higher currents up to 32A and power up to 15kW for demanding industrial setups. |
The Hager MM504N differs from the alternatives by offering specialized protection for low-current electric motors (0.4-0.63A) with a low power rating (0.18kW). It is best suited for compact industrial and engineering systems requiring precise protection for small motors. You should choose this device over general-purpose circuit breakers or higher-capacity alternatives if your electrical load parameters match its specific working range.
