Positive Temperature Coefficient (PTC) Circuit Breaker:  This type greatly increases its resistance when excessive current passes through it. The
excessive current heats the PTC device, as the device heats its resistance increases. Eventually the resistance gets so high that the circuit is effectively
open. Unlike the ordinary circuit breaker the PTC unit will not reset until the circuit is opened, by removing the voltage from its terminals. Once the
voltage is removed the circuit breaker will re-close within a second or 2.
