Main distribution boards and sub-distribution panels
When it may not be suitable
This circuit breaker is not intended for use in low-current residential applications where a 400A rating would be excessive and impractical. It is also not suitable for environments requiring specific environmental protections, such as high-moisture or explosive atmospheres, unless housed within an appropriately rated enclosure.
Key specifications
Rated current: 400A
Number of poles: 3
Breaking capacity: 50kA
Device type: Molded case circuit breaker
How to use
The Eaton LZMN3-A400-I should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is typically mounted within a distribution panel or switchgear enclosure. Ensure that all cable connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, the breaker can be operated manually via the front-mounted toggle mechanism to connect or disconnect the power supply.
What to consider before purchase
Verify that the 400A rating matches your system's load requirements.
Ensure the 50kA breaking capacity is sufficient for the prospective fault current levels at the installation point.
Confirm that the physical dimensions of the breaker are compatible with your existing switchgear or panel space.
Check that the installation environment meets the necessary temperature and humidity standards for industrial equipment.
Usage recommendations
Regular inspection of the terminal connections and the operational status of the breaker is recommended to ensure long-term performance. Always consult the technical documentation provided by Eaton for specific installation guidelines and maintenance intervals.
