Product Description

This unit is a Rockwell Automation Remanufactured Product. The shipping label carries shipping number R20G1AND156AA0NNNNN/A and serial number 15741298, which matches the serial number on the nameplate. A few characters of the shipping number are partly smudged on the label; the rest agrees with the nameplate catalog number 20G1AND156AA0NNNNN. Buyers should factor that provenance into their evaluation.

The Allen-Bradley 20G1AND156AA0NNNNN is a PowerFlex 755 AC variable frequency drive, Series A. The nameplate carries two separate voltage class ratings and the figures differ between them. On the 480V class the drive is rated 125 HP normal duty and 100 HP heavy duty, with an input range of 432 to 528V drawing 146.5A ND or 117.4A HD, an output range of 0 to 460V at a 60 Hz default base frequency, and continuous output of 156A ND or 125A HD. Overload capability on that class is 171.6A ND and 187.5A HD for 60 seconds, and 234A for 3 seconds on either duty. On the 400V class the drive is rated 90 kW ND and 75 kW HD, with an input range of 342 to 440V drawing 166.5A ND or 137.2A HD, an output range of 0 to 400V at a 50 Hz default base frequency, and continuous output of 170A ND or 140A HD.

The enclosure is UL Open Type / IP00 per the nameplate, reaching UL Type 1 only with a conduit plate and debris label, and UL Type 4X / IP66 at the rear with a 4X flange adapter kit. The nameplate shown is the custom catalog nameplate representing the options installed at the factory. Rockwell places a second nameplate behind the HIM with the equivalent base catalog number and the separate option list; that second nameplate has not been photographed, so the installed options are not confirmed. Power terminals are marked R/L1, S/L2 and T/L3 on the input and U/T1, V/T2 and W/T3 on the output, with a protective earth connection below them. The front face shows STS, ENET and LINK indicators, and no HIM is installed.

Original firmware is 13.003 per the nameplate, manufactured 27 March 2013 at FAC 1100 in the USA. Sold as surplus, untested; this unit has not been powered on or functionally tested by MRO Exchange. Buyers matching this drive for replacement or spare inventory should confirm the catalog number, the voltage class they are running, the firmware revision and the installed options against their existing installation.
