The part number 20DC261A0ENNBNNNN represents a robust adjustable-frequency AC drive in the Allen-Bradley lineup. Designed to work efficiently at an input voltage of 400V AC, this device effectively operates with three-phase power. It is rated to handle a significant current of 261 amps (normal duty), making it suitable for large and demanding applications.

The unit is housed in an IP20 rated enclosure, complying with NEMA Type 1 standards, which provides essential protection from dust and accidental contact. The human-machine interface is a blank cover, which simplifies the layout while still meeting operational requirements.

This AC drive does not include a brake, but it features an adjustable bus undervoltage trip that adds an extra layer of safety during operations. Thermal protection is ensured by a heat sink thermistor that is continuously monitored by a microprocessor, which triggers an overtemperature trip if necessary.

The 20DC261A0ENNBNNNN supports a logic control ride-thru of 0.25 seconds when the drive is inactive, preventing system faults from momentary power interruptions. Additionally, it provides power ride-thru capability that lasts for 15 milliseconds under full load conditions, ensuring stability and reliability during fluctuations.
