Overview
The Allen-Bradley SP-142510 is a transistor and snubber replacement kit engineered for the 1336VT variable frequency drive series. This component kit provides critical power switching and protection elements required to maintain reliable operation of 25 HP 1336VT drives operating at 380–460 VAC input. The SP-142510 kit supplies the semiconductor and snubber network necessary to handle power conversion in AC motor applications. Three kits are required per complete 1336VT drive installation.

Typical Applications
The SP-142510 kit is used in industrial motor control and variable frequency drive applications requiring semiconductor replacement or repair. Common uses include:
- 1336VT drive maintenance and repair operations
- Production machinery with three-phase AC motor control
- HVAC and pump systems requiring soft-start or speed control
- Conveyor and material handling equipment powered by three-phase motors
- OEM and retrofit installations where drive component replacement is necessary
Compatibility & Replacements
The SP-142510 is a direct component replacement for Allen-Bradley 1336VT drives. Cross-reference part numbers include 142510 and 1336-142510. This is a discontinued component; however, surplus and refurbished units remain available through authorized industrial distributors. When ordering replacement kits, confirm your drive frame size and horsepower rating. Three individual SP-142510 kits are required per standard 1336VT drive configuration. Installation requires power removal and trained technician service per Allen-Bradley safety guidelines.
