The trip coil has the whole circuit load amperage flowing through it. Thepurpose of the breaker is to only allow current up to its trip point. That is the only way that the breaker can sense if the current is within the limit rating. If the circuit load amperage becomes greater that the breaker rating it will trip. The trip coil that you refer to is a magnetic trip which senses the magnetic field that surrounds the wire. Breakers also have a thermal trip which senses a heat build up on the current flowing through it. If the breaker is in a high ambient temperature it will lower the rating on the breaker.

What is the continuous loop that an electric current flows through?
DC = direct current.
Which device designed to open an overloaded circuit and prevent overheating?
Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.A circuit breaker or fuse.
Is somthing that flows through an electric circuit an eletrical current?
Yes. Current consists of electrons flowing in a circuit.
How a circuit breaker prevent from too much current flowing into device?
The current (in question) flows through both the circuit AND the circuit breaker [they are in series]. Within the circuit breaker when the current exceeds the preset limit it will open the circuit thus stopping all current flow. There are two common ways of doing this 1) magnetism - a coil pulls a switch open 2) thermal - a bimetallic strip bends away from its contacts, which opens the circuit.
What are the differences between a Miniature Circuit Breaker and normal Circuit Breaker?
An air circuit breaker, or air-blast circuit breaker, is a type of circuit breaker used in high-voltage transmission/distribution systems. It uses compressed air to (a) operate its tripping mechanism, and (b) to extinguish the arc created by a fault current. A miniature circuit breaker is a type of circuit breaker used in low-voltage applications, such as the protection of lighting and power circuits in a domestic residence. It uses a spring to operate its tripping mechanism, and relies on the speed of operation to extinguish the arc created by a fault current. Apart from the fact they are both designed to interrupt a fault current, there is really no other similarity.
What device used to open a circuit if too much current flows through it?
A circuit breaker is a device used to open a circuit if too much current flows through it.
When dangerously high current flows through this overheated metal pushes the switch open to create an open circuit What is this?
A circuit breaker.
What flows through a complete circuit?
Current flows through a complete circuit.
What do circuit breakers and fuses have in common?
Both fuses and circuit breakers cut off a circuit from its power supply when the total current through the circuit exceeds the current rating of the fuse or circuit breaker, usually due to a short to ground or overloading of the circuit. Both use materials that respond to heat.
Why does an electrical breaker trip when you use a lot of appliances in the house?
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.
True or false The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit?
True
What is the continuous loop that an electric current flows through?
DC = direct current.
What flows through an electric circuit?
An electrical current.
What is a path through which electric current flows?
"circuit"
When dangerously high currents flows through a thin strip of metal melts which creates an open circuit and current stops flow?
This is the general description of how a circuit breaker operates.
What is the electric circuit where current flows through all parts of the circuit?
complex circuit
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
