Abstract:
The present invention provides an improved hybrid motor starter that extends the expected life of the main motor contacts of a standard contactor by reducing arcing during opening and closing of the main motor contacts and permits the use of physically smaller solid state switching devices and secondary contacts that have electrical ratings significantly lower than the standard contactor. The use of smaller solid state switching device and secondary contacts that have lower electrical ratings is permitted by minimizing the time at which these devices are exposed to full motor currents.
