How do I know if my overload protection relay is faulty?
If your overload protection relay is faulty, you may notice that it trips or disconnects the circuit even when the current is not too high. If this is happening, you should have the relay tested and replaced if necessary.
Can a faulty overload protection relay cause damage?
Yes, a faulty overload protection relay can cause damage to the circuit. It is important to have it tested and replaced if necessary to avoid this.
How do I replace an overload protection relay?
To replace an overload protection relay, you will need to:
- Disconnect the power supply to the circuit.
- Remove the mounting screws and remove the old relay.
- Connect the new relay to the circuit.
