A relay circuit is typically a smaller switch or device which drives (opens/closes) an electric switch that is capable of carrying much larger current amounts. Or a circuit which operates the coil or electronic actuator from one source and uses a separate power source to drive an isolated device. Generally speaking, a relay circuit is a circuit that uses a small mechanical switch or a semiconductor device (with associated circuitry) to energize a relay, which will then close a contact set to complete another circuit. This system is used by most people on a daily basis, and it is used to start a motor vehicle. The key switch (ignition switch) is turned to "start" and 12 volts (approximately) is applied to the starter solenoid (which is a big relay). The coil is energized, it shuts contacts, and the battery voltage is delivered through the heavy contact set (for high current capacity) to the starter motor. There are variations on this theme to which the term relay circuit can be applied, but the idea remains the same: a small switch of some kind controls switching in another (usually higher voltage and/or current) circuit. It could be argued that the telegraph is a relay circuit. Remember those old westerns? When a telegraph key is pushed down (thus completing the circuit), a remote (relay) coil is energized. The magnetic field created by energizing that coil pulls down an armature with the objective being to make a "click" instead of it being to close some electrical contacts. An early and dramatic application of the simple relay circuit, the telegraph, yes? A RELAY CIRCUIT DOES NOT IMPLY MASSIVE CURRENT SWITCHING. It is a means to isolate one source to another.
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
a transistor circuit for driving the coil of a magnetic relay.
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
A relay receives a signal about a change in voltage and current through its control circuit, which is typically isolated from the high voltage circuit. When the voltage or current in the high voltage circuit exceeds a certain threshold, it activates an electromagnetic coil within the relay. This coil generates a magnetic field that moves an armature, closing or opening the relay contacts, thus allowing or interrupting the flow of electricity in the controlled circuit. The relay effectively acts as a switch that responds to the changes in the high voltage circuit while maintaining safe isolation.
A relay race could be a good model of a series circuit. In any circuit, current flow is the daisy-chaining of electrons from atom to atom.

Remote-Control Circuit. Any electrical circuit that controlsany other circuit through a relay or an equivalent device.
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
When one electrical circuit controls another circuit through a relay, the first circuit is called the "control circuit." The control circuit operates the relay, which in turn switches the second circuit, known as the "load circuit," on or off. This allows for the control of high-power devices using a low-power signal.
Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.
The 59N relay may be tripping the breaker due to circuit overload, short circuit, or ground fault. Check for any faulty connections, damaged wires, or improper settings on the relay. Ensure that the relay is properly sized for the load it is protecting and troubleshoot any potential issues in the circuit.
