Horsepower Use the relevant hp code to correlate job data with the Variable Speed Drives Series III you want to order. The motor’s FLA must not exceed the published current output of the drive you select. Make sure to verify motor FLA in some applications, for example, cooling towers that utilize lower speed motors with 1200 rpm or 900 rpm. See Table2 to Table4 for the FLA of the VSD Series III. Voltage Bypass and disconnect models default to the 100K SCCR design as a function of hp, changing the order code character from number 1, 2, 4, or 5 to the corresponding 100K SCCR voltage code A, B, C, or D. For example, VS3-050-4-N1B-2 becomes VS3-050-C-N1B-2. Use the following guidance to generate the correct order code: •If you order 208 V or 230 V models that use 30 hp and larger, default to voltage order code A or B. •If you order 480 V models that use 50 hp and larger, default to voltage code C. •If you order any compact disconnect models (N1C), use the 100K SCCR order code A, B, C, or D. •If you order 575 V enclosed products, use the 100K SCCR order code D for voltage.Variable Speed Drives Series III: Open, Bypass, and Disconnect Models ProductBulletin 3 Note:Get the 100K SCCR option on any disconnect or bypass model across the hp range. Bypass configuration The bypass configuration two contactor manual bypass with isolation fusing and multi-color pilot light under order code F limits hp to the following: •208 V or 230 V models have a limit of 20 hp. •480 V models have a limit of 40 hp. •This is not applicable to 575 V models.

Open drives are a popular choice for installers retrofitting an existing field installation and for OEMs. Open drives are available in NEMA 1 and NEMA 12 enclosures. Compact disconnect drives add circuit protection to an open drive. The use of a compact disconnect drive is ideal when there is no branch circuit protection, if the existing control panels are too small to house the drive, or if they are strictly low voltage panels. For OEMs that add drives to existing equipment designs compact disconnect drives are also ideal. Compact disconnect drives are available in NEMA 1 enclosures only. Division 15, 16, or 17 specify bypass drives. Bypass drives are shipped to the job site for field installation. You can run the motor across the line without assistance from the drive with a bypass drive solution. The benefit of a bypass solution is that in the event of drive failure the equipment keeps running if on full speed operation. All bypass drives include a disconnect switch. Disconnect drives are the same form factor as a bypass drive and include a pilot light to indicate operation status. Disconnect drives are popular in pumping applications. Bypass and disconnect drives are available in NEMA 1, NEMA 12, and NEMA 3R enclosures. NEMA 3R enclosures are the only suitable enclosure type for outdoor or rooftop mounting.
