150-A97NB-NA

The Allen Bradley 150-A97NB-NA is engineered as a robust solid-state controller for applications requiring reliable motor control. It is operational within a voltage span of 380 to 460 volts AC and supports three-phase systems. With a current rating of 97 Amps, this controller can manage substantial loads with a maximum power capacity of 75 HP at 460 volts AC. Additionally, its performance translates to 45 kW at 380V and 55 kW at 415V.

The device is designed for versatility, operating effectively within a frequency range of 50 to 60 Hz. Control voltage requirements are set between 100 and 120 volts AC, making it compatible with standard control circuitry. One notable feature of the controller is its adjustable ramp time, allowing settings from 2 to 30 seconds, which can help mitigate mechanical stress on connected loads during motor start-up.

Built with an open-type enclosure rated IP00, the 150-A97NB-NA is ideal for indoor environments free from dust and moisture exposure. The solid-state controller provides a heat dissipation rating of 285 Watts, ensuring adequate thermal management during operation. Its operational temperature range from 0 to 50 °C offers flexibility in various conditions, while the storage temperature range of −40 °C to 85 °C further enhances its usability in disparate environments. The device also sustains relative humidity levels from 5% to 95% non-condensing, broadening potential applications in humid conditions.
