Key Features

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

·Three-stage trip protection with adjustable current and trip time: Users can set and adjust the release mechanism according to their load current requirements.

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

·Features "Pre-Alarm Number" indication: When the actual operating current passing through the circuit breaker reaches or exceeds the pre-alarm operating 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-acting current, the LED indicator on the circuit breaker's cover turns red.

·High current instantaneous tripping 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 release mechanism.
