The AC contactor uses the principles of alternate current to operate and is equipped with an iron core that leads to eddy current loss and hysteresis loss. To prevent this, the iron core is laminated with silicon steel plates. As there is no generation or depletion of eddy current, DC contactors require no such lamination to counter the loss.
Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against …
When properly applied, no matter how high the current drawn, the overload relay provides protection without tripping unnecessarily. See the figure Overload Relay Trip Curve for the motor heating curve and overload relay trip curve. The curves show the overload relay tripping before motor damage occurs. Overload Relay Trip Curve
