Webcircuit protection while the thermal portion reacts slowly to slightly increased currents, providing overload protection. However, motors contain a large amount of metal and heat and cool much more slowly than the conductors that are connected to it. For this reason, a thermal magnetic MCCB does not provide suitable overload protection for a motor. WebElectric motors are the backbone of modern automation. Motors convert electrical energy into mechanical energy, and the resulting motion and torque drives a load. The most effective motor control solution is the variable frequency drive, or adjustable speed drive. Drives vary motor input frequency and voltage to control motor speed and torque.
