  5. Installation and Operation Notes

  1. Correct selection: Ensure the breaker’s rated current and trip curve match the load and circuit requirements.

  2. Secure wiring: Tighten terminal connections firmly to prevent poor contact or overheating.

  3. Environmental considerations: Install in environments free from excessive humidity, dust, or corrosive gases.

  4. Avoid continuous overload: The breaker is designed for fault protection, not continuous overcurrent operation.

  5. Regular inspection: Periodically check breaker operation and condition.

  6. Accessory compatibility: When adding auxiliary or signal contacts, ensure compatibility with the breaker.
