The Allen-Bradley 150-A97NBD-8L4 is a robust SMC-2 series solid-state motor controller designed to handle up to 97 Amps of current. It operates within an input line voltage range of 380 to 460 Volts AC for three-phase systems at 50 to 60 Hertz. Featuring an open-type enclosure, the controller includes a 460 Volts AC protection module with snubber networks and Metal Oxide Varistors (MOVs) for safeguarding against high line transients and surges. Supporting various applications between 1 to 75 Horsepower and up to 55 kilowatts, this controller offers both standard series and interface option configurations, facilitating ready integration with or without electromechanical starters. Easy digital adjustments and optional direct control features enhance the flexibility of the setup. Certified by CSA and CE marked, the unit is compact at 336 x 248 x 230 millimeters, weighing approximately 10.5 kilograms, and is efficient with a peak heat dissipation of 285 Watts. For optimal operation, use 50 square millimeter cables for power connections and #1/0 AWG for interface terminals.
