| Products and Applications: How Circuit Breakers Work |
|
This cutaway view of a thermalmagnetic circuit breaker illustrates the typical internal workings of these circuit-protection devices
Thermal-magnetic circuit breakers combine the instantaneous trip ability of a magnetic breaker for shortcircuit currents with the overload tolerance of thermal breakers for normal motor-starting demands. When reset, the movable contact completes the electrical circuit between the stationary contact on the line terminal and the bimetallic strip. The pawl on the strip keeps the contacts engaged. Current flows from the movable contact through the bimetallic strip to the release arm and into the electromagnetic coil. The coil connects to the terminal supplying power to the load.
There are three ways to trip this circuit breaker. First, a prolonged high current flowing through the bimetallic strip creates heat. The strip begins bending from the heat because of the different coefficients of expansion between the two metals. When it bends enough the pawl releases the movable contact and spring tension snaps the contacts open breaking the circuit.
The second trip mechanism uses the electromagnetic coil as a solenoid. When current through the coil is high enough the solenoid core is pulled into the coil, pushing downward on the metal plate where the bimetallic strip is fastened.
As the metal plate is pushed down, the bimetallic strip is again pulled away from the movable contact popping it open.
The final trip mechanism places force on the solenoid core by pressing the manual release button.

E-T-A is the Worldwide Leader in Circuit Protection Technology
Circuit breakers are saftey-critical items. The same E-T-A products may be required to operate occasionally or very often during the life of the equipment they are protecting. Either way, operation must be dependable immediatley a fault occurs. Any failure to perform could have a disastrous consequences - endangering people and property.
E-T-A have been Designing Circuit Protection Since 1948
To meet the most stringent demands, E-T-A products are designed and manufactuered to the highest quality at every stage of the manufacturing process and is verified by the latest automatic test equipment and SPC techniques.
**NEW** ESX10 Electronic Circuit Protector
E-T-A Circuit Breakers announces the ESX10 Electronic Circuit Protector, a remarkably compact device combining purely electronic trip characteristics and active current limitation to allow selective dissconnection of loads connected to 24VDC power supplies. Selective load protection prevents complete shutdown of the system by quickly disconnecting the faulty path when an overload of short circuit occurs.
