Abstract:
1. A capacitor having a large current carrying capacity comprising a hollow core formed by a non-conducting tubular section, a capacitor winding wrapped around the tubular section, and a thermal cutoff device disposed within the hollow core, wherein the thermal cutoff device is configured to sense a predetermined temperature level within the hollow core and disable the current carrying capacity of the capacitor, the thermal cutoff device includes first and second conductors electrically connected to each other with a predetermined solder alloy, the first conductor includes a rest state that occurs after being subjected to a springing force in a lateral direction away from the second conductor, the first conductor forms an angle of A degrees with respect to the second conductor during the rest state, the first conductor is disposed on top of a spring for biasing the first conductor away from the second conductor, an end portion of the first conductor extends beyond an end portion of the spring for connecting the end portion of the first conductor directly to the second conductor, and the first conductor, the second conductor, and the spring are each separate elongated planar strips.
