Starter Breakers & Disconnects

Electrical codes require that motor control circuits must be provided with thermal protection and magnetic protection. Thermal protection protects the circuit against overload and locked rotor conditions. Magnetic protection protects the circuit against short circuit conditions. There are two methods of motor control system protection that are commonly used today. The 3-component system, where circuit breakers, magnetic contactors and thermal overload relays are installed to control and protect the motor, and the 2-component system, where only a Thermal Magnetic Circuit Breaker (TMCB) and contactor are used.

The 3-component system has the thermal protection and the magnetic protection in two separate units, which may lead to mismatching of correct specification when either of the units are replaced. This could lead to non-coordination of the protection devices. The 2-component system’s TMCB has a built-in overload relay and magnetic trip mechanism in one unit, reducing the vulnerability of mismatching of specifications.

Schneider Electric TeSys GB2 Motor Circuit Protectors are thermal-magnetic circuit protectors that enable reliable protection of industrial equipment control circuits, such as power supplies, PLCs, control circuits and all small devices capable of generating high current peak.
