Abstract
A thermal protection switch device may include: a power circuit that includes a phase line and a neutral line; a current sensor electrically connected to the phase line to detect the current flow in the phase line; a temperature sensor thermally coupled to the phase line to detect the temperature of the phase line; and another temperature sensor thermally coupled to the neutral line to detect the temperature of the neutral line. The device also includes a trip circuit configured to interrupt the phase line when activated and a controller configured to receive output signals from the above current and temperature sensors. The controller may activate the trip circuit to interrupt the phase line in response to determining that certain conditions have occurred.
