PTC thermistors are serially connected in a load circuit to protect motors, transformers, delicate electronic circuits, etc. from over-current/over-temperature conditions. The thermistors automatically returns to their normal protective function after fault removal. As opposed to plastic thermistors which degrades after several active cycle, our ceramic thermistors consistently retains the original state of properties after frequent On-Off cycles. |
