ABSTRACT: Protected potted metallized film capacitor. A protective system to prevent a dry metallized film capacitor from rupturing its case or catching fire in the event that an internal short or fault occurs within the capacitor section utilizes a fuse and a thermal protector connected in series with the capacitor section and within its case. The fuse serves to protect the unit from a fault-induced low resistance high current in-rush, while the thermal protector is triggered by a fault-induced high resistance low current. A heat reflective circumferential sheet and the postioning of thermal protector maximize its value in the protective system.
