description The invention discloses a high and low temperature compensation mechanism of a circuit breaker, which is characterized that the mechanism comprises a limit lock (1), the limit lock (1) is connected with a limit compensation sheet (2), and the limit compensation distance a between the limit compensation sheet (2) and the limit lock (1) is 0.15-0.55 mm. According to the invention, the temperature compensation mechanism is designed to compensate the maximum deformation displacement of the thermal release in the high and low temperature environment so as to ensure that the relative displacement of the thermal release and the unlocking mechanism is unchanged in the high and low temperature environment, and the high and low temperature environment test verification is carried out according to the GJB5885-2006 General Specification for Aviation Circuit Breakers, the maximum working environment temperature range of the product can reach-55 DEG C to + 125 DEG C, and the product temperature range index is advanced in C
