The SP-142510 kit is a spare part kit with a transistor and snubbers. It can be used for the replacement of faulty parts in the Allen-Bradley 1336VT drives with 25 Horsepower power output ratings and 380 to 460 Volts AC voltage ratings. Three SP-142510 kits are needed per 1336VT drive. The Allen-Bradley 1336VT drives are microprocessor-controlled variable frequency drives which are available in a wide range of power ratings. These drives support multiple input voltage ratings and they are available in multiple enclosure types to satisfy different industrial applications. Common reasons for failures which lead to the need for replacement parts such as the SP-142510 transistors include excessive ambient temperatures, incorrect or inadequate AC supplies, improper bypass, and the improper connection of output circuits to the motor.

The Allen-Bradley 1336VT variable frequency drives that use the SP-142510 kit should be installed in vertical orientations. The minimum clearance recommendations for the drives are 4 inches on the top and bottom sides and 2 inches on the left and right sides for ventilation. The drives should be installed so that they are easily accessible for maintenance. The location where the drive is installed should be at an altitude that does not exceed 1000 meters above sea level. The drives should be protected from corrosive elements such as gases and vapors. The relative humidity around the drives should be less than or equal to 95%. For drives with open enclosures, the ambient temperature for the heatsink on the drive should be less than 40 degrees Celsius. The ambient temperature for drive components like the SP-142510 kit should be kept below 50 degrees Celsius.
