Thermal Magnetic Motor Circuit Breaker

They install on a standard 35mm din rail and work with a variety of accessories to make wiring as easy as possible.

Thermal magnetic motor circuit breaker.

In case of overload or short circuit the breaker trips opening the circuit and protecting the conductors. The bimetal serves as a means of handling overcurrents. However engineers and technicians found some problems coming out with this method. Thermal magnetic circuit breakers contain two different switching mechanisms a bimetal switch and an electromagnet.

Molded case circuit breakers in individual enclosures are also being used in numerous applications. The motor protection circuit breaker can be considered a subtype of a thermal magnetic circuit breaker but with additional functions that are specially designed to protect electric motors. The series c circuit breaker is ideal for panelboards switchboards motor control centers and busway applications. In american homes today thermal magnetic circuit breakers are the most common type.

Available for systems up to 600 vac or 250 vdc with current ratings up to 800a. Thermal protection is used to guard the electric motor against overload. There are two commonly used methods of motor control system used in the industry. The first component is an electromagnet that is sensitive to large surges in electrical currents.

These are circuit breakers which utilize two components to detect electrical faults. Choose from a premier selection of trip units including thermal magnetic electronic and magnetic only switches. C3controls series 330 motor protection circuit breakers provide reliable overload and short circuit protection for all your motor control applications and are ideal for use in multi motor applications.

The basic working principle is similar to all other circuit breakers. An mccb provides protection by combining a temperature sensitive device with a current sensitive electromagnetic device. The traditional molded case circuit breaker uses electromechanical thermal magnetic trip units that may be fixed or interchangeable. The conventional method is the 3 component system where circuit breaker magnetic contactor and thermal overload relay are installed to control and protect the motor.

Both these devices act mechanically on the trip mechanism.
