The precision mechanism of the magneto-hydraulic circuit breakers is not affected by the ambient temperature, thus, it only reacts to changes in current of the protected circuit. They have no warm-up time, shortening the reaction time to overload, and must not cool to be reset after an overload. These circuit breakers have a mechanism that prevents manually maintaining contact during fault conditions, and comply with international safety standards and standard dimensions, for easy assembly.
We can say that they have all the advantages of classic thermal magnetic circuit breakers, and none of their drawbacks.
