Multiple powers to choose from
Thermal protection trips when there is an overload condition – The excessive current heats up a bimetallic contact that expands until the current is interrupted. Thermal response is slow to allow short-duration over current conditions, which are normal in some devices such as electric motors during startup.
Magnetic protection trips in response to the high currents present during electric faults – The current causes a strong magnetic field through induction, which is used to open a contact and interrupt the circuit. The response is immediate, to minimize the harmful effects of electric faults.
