Breaker, PowerPacT M, 400A, 3P, 600VAC, 18kAIC, I-Line, ET 1.0, 80%, ABC

PowerPact M-frame molded case circuit breakers provide improved performance and a compact solution for applications up to 800A. They complement the existing PowerPact P- and R-frame circuit breakers and replace the traditional MA/MH circuit breakers with a smaller footprint and competitive cost. PowerPact M-frame molded case circuit breakers are available in 300, 350, 400, 450, 500, 600, 700, and 800A ratings. PowerPact M-frame molded case circuit breakers have built-in electronic trip unit type ET 1.0 provides better accuracy than standard thermal-magnetic trip units. The ET 1.0 trip unit cannot be field replaced, nor does it allow adjustment of the trip point setting. (It is considered an electronic equivalent of a thermal-magnetic circuit breaker.)
