The AM2R-D3-LC07D-A-50-2 is a 2-pole, front-mount hydraulic-magnetic circuit breaker from the AMR series, designed for overcurrent protection. It features a series trip internal circuit with a current rating of 50 Amperes and is suitable for both 50/60 Hz AC and DC applications. This model is configured with a medium time delay curve (Curve 2) to handle 8x inrush currents, has 10-32 stud terminals, and is UL 1077 recognized for operation up to 250V AC or 80V DC. The breaker includes a white handle on each pole and operates reliably across an extreme temperature range of -40°C to +85°C without derating. Its robust design and stable trip characteristics make it ideal for demanding applications in industrial, telecom, rail, and marine environments.
