A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
No, you could use a GFCI circuit breaker instead.
An alternative to using a fuse is to use an electrical circuit breaker.
You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.
Craig, Please refer to Australian Standard AS3000:2007 for the answer.

since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
To test a circuit breaker, you can use a multimeter to check for continuity and proper voltage. First, turn off the power to the circuit breaker. Then, use the multimeter to test for continuity by placing the probes on the terminals of the circuit breaker. If there is continuity, the circuit breaker is functioning properly. Next, test for proper voltage by turning on the power and checking if the voltage is within the specified range. If the circuit breaker passes both tests, it is functioning properly.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
To use a circuit breaker effectively to protect electrical circuits, follow these steps: Install the circuit breaker correctly according to the manufacturer's instructions. Make sure the circuit breaker is the appropriate size and type for the electrical load. Regularly test the circuit breaker to ensure it is functioning properly. If a circuit trips, investigate and address the cause before resetting the breaker. Do not overload the circuit by plugging in too many devices or appliances. Consider hiring a professional electrician for installation and maintenance if needed.
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
