Electronic Trip Unit Circuit Breaker. Both type of circuit breakers. The micrologic trip unit samples the current waveform to provide true rms protection through the 15th harmonic.
Micrologic electronic trip circuit breakers provide the same basic functions as standard thermal magnetic circuit breakers. Wide range of trip units to protect most applications. Micrologic trip protection from 250 600 a up to 600 vac.
3 and 4 pole design.
Powerpact l frame molded case circuit breakers 600 a a flexible high performance offer certified to global standards. In addition to this electronic tripping units offer more tripping criteria which are not feasible with electromechanical releases. Electronic trip circuit breakers are limited to ac systems because the electronic trip system uses current transformers to sense the current. Micrologic electronic trip circuit breakers provide the same basic functions as standard thermal magnetic circuit breakers.
