The t11 is easy to install with snap in mount and quick connect terminals.
Magnetic trip circuit breaker.
Schurter t11 circuit breaker is a snap in 1 pole thermal circuit breaker that offers positively trip free release.
Excessive electrical currents will heat the bimetallic strip enough to bend it towards a trip bar that turns the circuit off.
Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume.
There are other devices able to break a circuit during a surge or short circuit each with its own limitations.
Thermal magnetic tripping units the thermomagnetic trip unit consists of two parts.
The second component used in a thermal magnetic circuit breaker is a thermal bimetallic strip that responds to prolonged low level electrical surges or overloads of electrical currents.
The bimetal serves as a means of handling overcurrents.
In a thermal magnetic circuit breaker the trip unit includes elements designed to sense the heat resulting from an overload condition and the high current resulting from a short circuit.
The trip unit is the part of the circuit breaker that determines when the contacts will open automatically.
With normal current the electromagnet will not have enough attraction to the trip bar to move it and the contacts will remain closed as shown in figure 2 20 view a.
Suitable for use in power tools household equipment power supply and chargers and industrial applications.
Electronic trip breakers are typically built as molded case circuit breakers mccb which means they require more space than a miniature plug in circuit breakers.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected.
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.
A magnetic trip element circuit breaker uses an electromagnet in series with the circuit load as in figure 2 20.
This trip unit is intended for the protection against overloads.
The magnetic field moves a switch tripping the breaker and clearing the fault.
Many thermal magnetic breakers are rated for use in both ac and dc applications but electronic breakers with cts are exclusive for ac circuit protection.
Overloaded circuits loose or faulty wiring and lightning can cause the circuit breaker to trip.
The thermal trip unit made up by a bimetal thermal device which actuates the opening of a circuit breaker with a delay depending on the overcurrent value.
The strength of the.
The magnetic protection mechanism is calibrated to trip with high magnitude fault currents but does not respond to.
