20DD46020ENNB1CEL

The Allen-Bradley 20DD46020ENNB1CEL is an adjustable frequency AC drive suitable for industrial applications. It requires a three-phase power supply operating at 480V AC. This unit has a significant normal-duty current capacity rated at 460 amps, making it ideal for demanding load requirements.

Housed in an enclosure with IP20 protection compliant with NEMA Type 1 standards, this drive prepares itself for operation in typical indoor environments. Instead of a display, it incorporates a blank cover for the human-machine interface, simplifying installation.

The drive does not feature a built-in braking system, which may be suited for specific installations where external braking solutions are implemented. The bus undervoltage trip is adjustable, allowing customization based on operational needs. Thermal protection is vital for this unit; therefore, it includes a heat sink thermistor monitored by a microprocessor to prevent overheating.

To enhance reliability, this drive can sustain a logic control ride-thru period of 0.25 seconds when it is not actively running. Furthermore, it provides power ride-thru capability for 15 milliseconds at full load, ensuring continued operation during transient conditions. The 20DD46020ENNB1CEL drive is engineered for longevity and efficiency in high-demand environments, making it an important component for automation systems.
