The AM1-B3-A-15-3 is a single-pole, front-mount hydraulic-magnetic circuit breaker designed for overcurrent protection. It features a series trip internal circuit for 50/60 Hz applications, configured with a short time delay curve (Curve 3) to handle an inrush current of up to 8 times the nominal rating. This model is UL 1077 recognized for operation up to 250V AC or 80V DC with a maximum current rating of 100A. The hydraulic-magnetic technology ensures stable trip characteristics across an operating temperature range of -40°C to +85°C, making it a reliable choice for industrial, telecom, and marine applications.
