Frequently Asked Questions (FAQ)

1. What is the main purpose of the SJK47LE-63 circuit breaker?
It is designed to provide overcurrent protection and residual current (earth leakage) protection in electrical circuits.
2. What are the available rated currents for this series?
The series supports a wide range of rated currents, typically from 6A to 63A depending on the specific model requirements.
3. Can this circuit breaker be installed in 400V systems?
Yes, models with 3 or 4 poles are designed to operate at a rated voltage of 400V.
4. What is the breaking time for residual current at IΔn?
The breaking time at rated residual operating current is less than 0.1 seconds, ensuring rapid protection.
5. What is the recommended torque for terminal connections?
The screw-clamp terminals should be tightened to a torque of 2N·m to ensure a secure connection.
