MJA36800 3P, 600V, 800A I-LINE MCCB,
Circuit breaker, PowerPacT M, 800A, 3 pole, 600VAC, 25kA, 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.) They also have fIxed long-time and adjustable instantaneous protection (2 to 10 times nominal ampere rating) is standard. Powerpact M-Frame breakers have the same dimensions, common mounting, bussing, cabling and door cut-out as PowerPact P-frame circuit breakers. This PowerPact M, circuit breaker has a rated current of 800A and a rated operational current of 600VAC and is an plug-in mounted breaker. This 3-pole breaker has a breaking capacity of 25kA@600VAC with an 80 % continuous current rating. This breaker complies to UL listed, IEC & CSA standards. This product has an electronic ET 1.0 trip unit trechnology and a magnetic tripping current of 1600-8000A. Dimensions for this product are 12.86 in (H),8.27 in (W), 5.77 in (D). This product comes with an 18 month warranty.
