How many coils in air circuit breaker?
There are three coils in Air circuit breaker.. 1.Solonoid coil 2.Moving coil 3. fixed coil
What is the purpus of a circute breaker?
The purpose of a circuit breaker is to protect electrical circuits from short circuiting.
Why two trip coil require in breaker?
Transformer is HEART of the substation and Circuit Breaker is the LUNGS of the substation.At faulty condition, large amount of current will flow.so trip function is very important at that timeone coil is faulty means, another one coil will trip the connection to the healthy circuit.
What is the purpose of a Pushmatic breaker?
It is a residential circuit breaker to increase your circuit boards power. They are no longer widely available but they can be purchased from eBay and other on-line retailers.
How much current flows through circuit breaker trip coil?
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.

Circuit breaker are for the same purpose as?
... fuse.
Why use shunt release in circuit breaker?
A secondary shunt releases (extra trip coil) is used forelectrical tripping of the circuit breaker by protectiverelays or manual control devices when more than onetrip coil is required.
What is the metal piece on the circuit breaker preventing it from tripping?
A circuit breaker is designed so that it will trip when the electric current is too high. That is the purpose of a circuit breaker. If there is a metal piece on the circuit breaker that prevents it from tripping, it is useless. Perhaps someone has altered it.
How do you work air circuit breaker?
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.
How many ampacity rating do a circuit breaker need for the general purpose circuit?
Usually a 15 or 20 amp breaker is sufficient
What is the purpus of a circute breaker?
The purpose of a circuit breaker is to protect electrical circuits from short circuiting.
What is the part of a circuit the closes or opens the circuit?
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
What are the devices contain in a circuit breaker?
The devices contained in a circuit breaker consist of a bi metal strip for over load protection and a small wrap of wire in the form of a coil for magnetic short circuit trip.

What is the purpose of a seal-in contact?
This is a small electromagnet whose coil is in series with the relay contacts and whose contact is in parallel with them. The electromagnet is energized, closing its contacts in parallel with the relay contact as soon as the trip coil is energized, and drops out when the circuit breaker opens.
