The AM3R-C3-LC07D-A-30-1 is a three-pole, front-mount hydraulic-magnetic circuit breaker from the AMR series, engineered for overcurrent protection. It features a series trip internal circuit with a current rating of 30 amperes and is specifically configured for 400 Hz frequency operation. This model is equipped with a handle on each pole, black handles with "I/On O/Off" markings, and 10-32 stud terminals. It utilizes a long time delay curve (Curve 1) designed to handle an 8x inrush current, preventing nuisance tripping in demanding start-up conditions. The breaker is UL 1077 recognized with maximum voltage ratings of 240V at 400Hz and 80V DC. Its robust design, which is unaffected by ambient temperature extremes, makes it suitable for demanding applications in industrial, telecom, military, and marine environments.
