Product Description
The Allen-Bradley 150-B97NBDB, a 97-Amp solid-state motor controller from the Bulletin 150 SMC Dialog Plus series, operates on 200-600VAC, delivering 1-1000 Amps output. This open-enclosure controller, certified by CSA, CE, CCC, UL 508, EN/IEC 60947-1, and CSA C22.2, features standard pump control and optional features like preset slow speed and accu stop. It offers six motor control modes, including current limit, dual ramp start, and energy saver. At 460VAC, it handles 5-500 HP, accepting 200-460VAC three-phase input (50-60 Hz) and using 100-240VAC control voltage. Short-circuit protection is provided by a 350A fuse. It dissipates a maximum of 285W, weighs approximately 23 pounds, measures 12 x 9.77 x 10.09 inches, and operates between 0-50C.
Is Your Device Showing These Signs?
The Allen Bradley 150-B97NBDB commonly experiences issues such as nuisance tripping due to incorrect overload settings or faulty trip units.
