Key Features

· The RMM1E electronic molded case circuit breaker features three-stage protection, and the type B circuit breakers, when connected to other short-circuit protective devices on the same circuit, provide selective coordination under short-circuit conditions.

· Features three-section protection action current and timing selection: Users can adjust the trip unit according to their load current requirements.

· Self-powered: The electronic release is powered by the circuit breaker itself, with the current signal and power supply for the release coming from the current transformer installed within the circuit 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 lights up yellow.

· Overload indicator; when the load current exceeds the overload long-time-acting current, the LED indicator on the circuit breaker cover turns red.

· High current instantaneous trip function; when the circuit breaker closes or during operation, it will trip directly from the electromagnetic release mechanism upon encountering a short circuit with a high current (≥201A).
