Key Features

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

· Three-stage protection action current and timing selection: Users can adjust the release mechanism 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 derived from the current transformer installed within the circuit breaker.

· Indicates "trip number": When the actual operating current flowing through the circuit breaker reaches or exceeds the pre-alarm trip current Iro, the "pre-alarm" LED indicator on the circuit breaker cover lights up yellow.

· Overload indicator; when the load current exceeds the overload long-time-delay trip current, the LED indicator on the circuit breaker's front cover will light up red.

· High current instantaneous tripping function: When the circuit breaker is closed or in operation, it will trip directly through the electromagnetic release mechanism upon encountering a short circuit with a high current (≥201A).
