Abstract:
1. A capacitor providing a thermal alert comprising: a wound film capacitor for carrying a large current when coupled to an AC generator, and the wound film capacitor including a hollow core extending from one end to another end of the capacitor, a thermal switch disposed in the hollow core for sensing a predetermined temperature, a light indicator coupled to the thermal switch, a housing integrally formed from an upper cover and a lower cover for housing the wound film capacitor, the thermal switch and the light indicator, and the upper cover of the housing formed from translucent material, wherein the thermal switch is configured to disconnect the wound film capacitor from the AC generator upon reaching the predetermined temperature, and activate the light indicator to emit a light, the upper cover is effective in transmitting the light from inside the housing to outside of the housing, and the thermal switch includes a first end connected by a first conductor to the AC generator and a second end connected by a second conductor to the wound film capacitor, and the first and second conductors are strips of flexible metal for conducting a current of at least 50 amperes to the switch.
