The AM1S-D3-A-15-2 is a single-pole hydraulic-magnetic circuit breaker from the AM/S series, designed for robust equipment circuit protection. It features a series trip configuration with a current rating of 15 amperes and a medium time delay (Curve 2) characteristic suitable for general-purpose applications. This breaker is rated for operation at up to 250V AC (50/60 Hz) or 80V DC and utilizes hydraulic-magnetic technology, which ensures its trip point is unaffected by ambient temperature changes. As a UL 489 Listed device, it is ideal for demanding applications requiring precise overload protection, such as transformer protection, capacitor loads, and industrial controls.
