Dissipates braking energy Prevents drive overvoltage 25 Ohm resistance 1400W power handling For VFD applications

Product description

The Allen Bradley 20P-RES-GEF-A0 is a dynamic braking resistor designed to dissipate excess energy during motor deceleration. It features a resistance value of 25 Ohms and a power rating of 1400 Watts. This resistor is crucial for applications where rapid motor stopping is required, preventing overvoltage conditions in the drive.

This component is typically used in conjunction with variable frequency drives (VFDs) in applications such as hoists, cranes, elevators, and high-inertia loads that need controlled and rapid stopping. It helps to extend the life of the drive components and ensure safe operation.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the 20P-RES-GEF-A0. We provide quality surplus components to help you maintain your equipment efficiently and cost-effectively.
