Key Features

The RMM1E electronic molded case circuit breaker features three-stage protection functions. It has selective coordination with other short-circuit protection devices connected in the same circuit when operating under short-circuit conditions, using circuit breakers of category B.

· Features three-stage trip protection current and trip time selection: Users can adjust the trip unit according to the load current requirements.

Self-powered: The electronic release is powered by the circuit breaker itself, with the current signal and the release's power supply coming from the current transformer installed within the breaker.

· Features a "pre-alarm count" indicator: When the actual operating current passing through the circuit breaker reaches or exceeds the pre-alarm trip current Iro, the "pre-alarm" LED indicator on the circuit breaker cover turns yellow.

· Overload indicator; when the load current exceeds the overload long-time delay action current, the LED indicator on the circuit breaker cover will turn red.

· High current instantaneous trip function, when the circuit breaker is closed or in operation, upon encountering a short circuit with high current (≥201A), the circuit breaker is directly tripped by the electromagnetic trip mechanism.
