Usage Instructions

How to Use the Component in a Circuit

  1. Identify the Input and Output Terminals:

    • Connect the Line 1 and Line 2 inputs to the power source.
    • Connect the Line 1 and Line 2 outputs to the load (e.g., an appliance or another circuit).
  2. Mounting the Circuit Breaker:

    • Secure the circuit breaker onto a DIN rail or panel mount as per the installation requirements.
  3. Wiring:

    • Ensure that the wiring is done correctly and securely to avoid loose connections.
    • Use appropriate wire gauges as per the current rating of the circuit breaker.
  4. Testing:

    • After installation, test the circuit breaker by turning it on and off to ensure it operates correctly.
    • Check for any signs of overheating or unusual noises.

Important Considerations and Best Practices

  • Safety First: Always turn off the main power supply before installing or servicing the circuit breaker.
  • Correct Rating: Use a circuit breaker with the appropriate current rating for your application to prevent nuisance tripping or insufficient protection.
  • Regular Maintenance: Periodically inspect the circuit breaker for signs of wear or damage and replace it if necessary.
  • Proper Grounding: Ensure that the circuit is properly grounded to prevent electrical shocks and enhance safety.

Troubleshooting and FAQs

Common Issues Users Might Face

  1. Circuit Breaker Tripping Frequently:

    • Cause: Overload or short circuit in the connected circuit.
    • Solution: Check the connected devices for faults and ensure the total current does not exceed the breaker's rating.
