Key Features

· The RMM1E electronic molded case circuit breaker features three-phase protection function, and the circuit breakers of type B used in conjunction with other short-circuit protection devices connected to the same circuit have selective coordination under short-circuit conditions.

· Featuring three-stage trip current and trip 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 sourced 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-delayed trip current, the LED indicator on the circuit breaker cover will light up red.

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