20AC072A0NYNADC0

The Allen-Bradley 20AC072A0NYNADC0 variable speed drive provides a compact design that facilitates its installation and start-up processes. It combines a NEMA Type 1 enclosure with a panel-mounted mechanism that provides mobility. This enclosure protects the most important parts of the drive and it prevents users from coming into contact with dangerous parts. The Allen-Bradley 20AC072A0NYNADC0 variable speed drive belongs to the PowerFlex 70 series of drives and it features a voltage of 400 Volts AC and a frequency of 50 Hertz. Both of these values are intended to be used in 3-phase applications. The installation process of the Allen-Bradley 20AC072A0NYNADC0 variable speed drive is somewhat complex since it requires that the drive be grounded, including all its parts and connections. Even if it is included in a cabinet, there must be a single point connected to it.

In order to prevent electromagnetic interference, it is also important to shield all the cables and connections. The recommended cable types are those intended for installations that go from 200 to 600 Volts AC and for control, use the I/O copper cables with a rating of 75 degrees Celsius. It is also recommended that when mounting the Allen-Bradley 20AC072A0NYNADC0 variable speed drive, clearances are left between other drives or equipment that might block the air flow. This is done in order to maintain the recommended temperature and avoid overheating. Another useful recommendation is to install a circuit breaker or fuse that provides protection against short circuits or abnormal line transients. The Allen-Bradley 20AC072A0NYNADC0 variable speed drive works with enhanced control I/O and a DeviceNet communication slot.
