MA36400 - 400 Amp Circuit Breaker Description
MA36400 - 400 Amp Circuit Breaker
When you're matching a breaker for an existing I-Line panelboard, the nameplate details matter. The MA36400 is a 400-amp, 3-pole MA molded case circuit breaker with thermal-magnetic operation, a 60Hz frequency rating, and a 40°C rating. Its interrupting ratings are clearly defined at 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, making it easier to compare the breaker against the electrical requirements of the existing installation. Physical fit is just as important on replacement jobs. For legacy equipment that calls for these specifications and an MA-type breaker for an I-Line panelboard, the MA36400 can be considered a form, fit, and functional replacement candidate when all application requirements match. Its solid molded-case construction is built to last when properly selected, installed, and maintained.
