How you determine correct size varistor for protect system which work with 220v AC?
You use varistor wich has the max voltage for that aplication example:vacuumcleanermax allowed voltage is 240v ac so you chose aprox. 250 V varistor.
What is virestor?
Varistors are often used to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when triggered
Why a circuit is protected by a circuit breaker?
1. protection against fire hazard from a short-circuit. A short-circuit can be caused by a loose wire, faulty insulation, or faulty wiring. A short-circuit will cause the wires to heat up rapidly, presenting a fire hazard. 2. protection against circuit overloading. Too much current in a wire caused by overloading (plugging in too many high-power appliances, for example) can cause overheating, presenting a fire hazard. Most circuit breakers have a "slow-blow" mode that breaks the circuit if overload continues for too long. 3. on grounded appliances (which have the third prong on the plug), the ground is connected to all exposed conductive material on the appliance. In the event that a loose wire contacts the exposed metal, a short-circuit will occur, and the power will be cut. This protects against accidental electrocution. Circuit breakers do not protect against fire hazards from inferior gauge of wire, glow-faults, or arc-faults. Most do not protect against electrocution hazards from ground-faults (although some do).
Which type of circuit is used in zener diode?
A Zener diode is typically used in a reverse-bias configuration within a voltage regulation circuit. This circuit ensures that the Zener diode maintains a constant output voltage, even when the input voltage or load conditions vary. It is often implemented in simple power supplies to provide stable reference voltages or to protect sensitive components from overvoltage conditions.

What would have caused your 40 amp fuse to blow?
What Causes Any Fuse to "Blow?"The cause is what fuses were invented and are used for:to detect and protect against SHORT CIRCUIT conditions, and /or CIRCUIT OVERLOAD conditions.
What protects against circuit failure?
Two examples of how to protect against circuit failure are fuses and circuit breakers.

What is a fusible resistor?
A resistor designed to protect a circuit against overload.
Why every electric circuit needs a fuse?
The fuse is designed to protect the circuit under fault conditions to aleviate damage
What do fuses and circuit breakers protect circuits from?
They protect the downstream components from spikes in the eletrical system.CommentFuses and circuit breakers do not protect against 'spikes', which are near-instantaneous voltage increases. Fuses and circuit breakers are overcurrent protection devices, which protect appliances against excessive current due to overloads or short circuits. CommentFuses and circuit breakers are used to protect the wire feeder that supplies the load. A load could be connected to a circuit that would cause an increase of amperage above what the wire is rated for. If this condition happens the fuse or circuit breaker will open the load from the supply service.
The first measure you should take to help prevent damage against electrical problems is to do what to the circuit?
Protect the circuit with an OCPD, an over current protection device, such as a circuit breaker or fuse.

Two examples of how to protect against circuit failure are fuses and circuit breakers. Skin protects the inside of the body from bacteria. If it weren't for skin, we would get infections way too easily and certainly would not be able to survive. Not only just bacteria, but from
What is a amperage relay?
An amperage relay is an electrical device used to activate or deactivate a circuit based on the current flowing through it. It is designed to protect the circuit from overload or short-circuit conditions by opening or closing the circuit when the preset amperage level is exceeded.
