Key Features

· The RMM1E electronic molded case circuit breaker features three-phase protection function and has selective coordination with other short-circuit protection devices connected in the same circuit when operating under short-circuit conditions.

· Three-stage trip protection current and time selection: Users can adjust the circuit breaker settings according to the load current requirements.

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

· A "trip number" indicator is provided: 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 will light up in yellow.

· Overload indicator included; when the load current exceeds the trip current of the overload delay, the LED indicator on the circuit breaker cover will light up red.

· High current instantaneous trip function; when the circuit breaker is closed or in operation, it will directly trip off the circuit breaker upon encountering a short circuit with high current (≥201A).
