When it may not be suitable
This circuit breaker is not intended for residential applications where lower current ratings are standard. It is also not suitable for environments requiring specialized protection features beyond standard thermal-magnetic overload and short-circuit capabilities, such as specific earth-leakage protection without additional modules.
Key specifications
Rated current: 400A
Number of poles: 3
Breaking capacity: 50kA
Technology: Thermal-magnetic
Design: Molded case circuit breaker
How to use
The device should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is mounted within a distribution board or enclosure, ensuring that all connections are tightened to the specified torque settings to prevent overheating. Once installed, the breaker can be manually operated using the front-facing toggle to connect or disconnect the power supply as needed for maintenance or system isolation.
What to consider before purchase
Verify that the 400A rating matches your system load requirements
Ensure the 50kA breaking capacity is sufficient for your installation's short-circuit current levels
Confirm the physical dimensions are compatible with your existing switchboard space
Check that the 3-pole configuration aligns with your electrical network topology
Usage recommendations
Regular inspection of the terminal connections and periodic testing of the tripping mechanism are recommended to ensure long-term operational safety and performance. Always consult the technical documentation provided by the manufacturer for specific installation and maintenance guidelines.
