Default Why use a contactor?

The best argument for using a contactor in a small bandsaw, is that
you can get proper thermal overloads to protect the motor.


This is more of a factor with three phase motors, where a motor
once started will continue to run if one phase of power fails, but the
current drawn in each remaining winding will be higher, and will be
likely to burn out the motor. (And he was going to add a 240 VAC single
phase motor to the bandsaw in question.)


No, on bandsaw, the main problem is that it runs unattended and can
easily get stuck.
