20DD300A0ENNNNBUE

The part number 20DD300A0ENNNNBUE is an adjustable frequency AC drive by Allen-Bradley, designed for 480V AC industrial applications. This unit is capable of handling a significant input current of 300 amps and operates in a three-phase system. Its compact design is housed in a NEMA Type 1 enclosure rated at IP20, ensuring adequate protection for indoor environments. The human-machine interface consists of a blank cover, indicating a straightforward installation without complex controls. }

For safety and reliability, the drive features an adjustable bus undervoltage trip, which can be configured to protect the system from low voltage conditions. To monitor thermal performance, the drive incorporates a heat sink thermistor, actively overseen by a microprocessor that can trigger an overtemperature trip if necessary.

This drive also boasts an efficient logic control ride-thru capability of 0.25 seconds when the system is not actively running, ensuring operational stability during brief power interruptions. Furthermore, power ride-thru functionality can sustain operation for 15 milliseconds under full load conditions, enhancing reliability in fluctuating power situations. A quick start guide is included to assist users during initial setup, facilitating a smooth integration into existing control systems.
