Selection and cooperation: YCM3E electronic shell circuit breaker has three-stage protection function, and the use of Class B circuit breaker has selective cooperation with other short-circuit protection devices connected in the same circuit under short-circuit conditions;

It has three stages of protection action current and action time selection: users can adjust the settings of the release according to the load current requirements;

Self powered: The electronic release is powered by the circuit breaker itself, and the current signal and the power supply for the release come from the current transformer installed inside the circuit breaker;

Equipped with a "pre alarm" indicator: When the actual operating current flowing through the circuit breaker reaches or exceeds the pre alarm action current Iro, the "pre alarm" LED on the circuit breaker cover indicates yellow;

Has overload indication; When the load current exceeds the overload long delay action current, the LED on the circuit breaker cover indicates in red;

High current instantaneous tripping function: When the circuit breaker is closed or in operation, in the event of a short circuit and high current (>20lnm), the circuit breaker will be directly tripped by an electromagnetic tripping mechanism;

Installation has interchangeability: the external dimensions are the same as those of YCM11 series molded case circuit breakers.
