Allen Bradley 1333-ZAA

The 1333-ZAA is a variable frequency AC drive from Rockwell Automation’s Allen Bradley. The drive is part of the 1333 Series D family of adjustable frequency drives. The 1333-ZAA has a 0.5 Horsepower rating and a power rating of 0.37 kilowatts.  The drive operates at an input voltage of between 200 and 230 Volts AC. Additionally, the 1333-ZAA has an input and output current of 6.2 and 2.6 Amperes respectively, when the input voltage comes from a single-phase power supply at a frequency of 50 Hertz. When the input voltage comes from a 3-phase supply, the 1333-ZAA variable frequency Alternating Current drive has an output and input current rating of 3.2 and 4.1 Amperes respectively at a frequency of 50 to 60 Hertz. The 1333-ZAA adjustable frequency drive dissipates 273 BTU per hour in both a single and 3 phase voltage supply. Since the 1333-ZAA is a variable frequency drive, its minimum and maximum frequency ranges are programmable from a minimum limit of 0 to a maximum of 400 Hertz (remote frequency command) and between 0.5 to 400 Hertz on a local frequency command.

The 1333-ZAA, as with the 1333-AAA and 1333-YAA adjustable frequency drives, is protected by a Bussmann FRS-R-15 time delay fuse. The 1333-ZAA variable frequency drive should be mounted in an enclosure that meet conditions specified in the NEMA type 1/IP20 guidelines. Additionally, as with other drives in the 1333 series, the 1333-ZAA should not be operated at altitudes exceeding 1,000 meters without derating. Note that the start, stop, auxiliary interlock, and speed reference control inputs must be available to ensure proper function of the 1333-ZAA together with any drive in 1333 series.
