Allen-Bradley 150-B97NBR SMC Dialog Plus™ Smart Motor Controller 75HP

The Allen-Bradley 150-B97NBR is a SMC Dialog Plus™ Smart Motor Controller designed for 75 HP motors operating at 480V AC. This soft starter provides advanced motor control functions, improving operational efficiency and extending motor lifespan by reducing mechanical and electrical stress during startup and shutdown. Key Specifications: Current Rating: 97 A Voltage Range: 200 – 460V AC, 3-phase, 50/60 Hz Control Voltage: 24V AC/DC Operating Temperature: 0°C to 50°C Storage Temperature: -20°C to 75°C Altitude Rating: Up to 2000 meters Operational Modes: Soft Start: Gradual voltage increase to reduce inrush current and mechanical stress. Current Limit Start: Restricts startup current to protect electrical systems. Dual Ramp Start: Offers two acceleration ramps for different load conditions. Full Voltage Start: Allows across-the-line starting when needed. Soft Stop: Gradual voltage decrease for smooth deceleration, preventing sudden motor shutdown.
