Electrical surges can cause short.

Magnetic circuit breaker diagram.

The majority of circuit breakers are thermal magnetic which means they accomplish electrical protection by combining two mechanisms that respond to heat and magnetic fields respectively. A magnetic circuit breaker is a safety device designed to cut an electrical current in the event of a power surge thus protecting electrical equipment and circuitry from damage. So in case of a magnetic circuit breaker a solenoid or an electromagnet is attached to the trip unit. There are other devices able to break a circuit during a surge or short circuit each with its own limitations.

Thermal magnetic circuit breaker definition. Two mechanisms are used simultaneously to offer an end result that combines the response characteristics of each but the goal of both is the same. Protecting the conductors and equipment connected to the. Circuit breakers may also use the higher current caused by the fault to separate the contacts such as thermal expansion or a magnetic field.

Small circuit breakers typically have a manual control lever to switch off the load or reset a tripped breaker while larger units use solenoids to trip the mechanism and electric motors to restore. The function of the solenoid or the trip unit is to generate a magnetic field. Circuit breakers cbs are designed to carry 100 of their rated current yet the national electric code nec dictates an 80 application. 2 0 circuit breaker design.

This is done when the current passes through the solenoid magnetism develops in it due to changing magnetic flux and a magnetic field is created around the solenoid. Overloaded circuits loose or faulty wiring and lightning can cause the circuit breaker to trip. These are circuit breakers which utilize two components to detect electrical faults.
