1. Product Name

Allen Bradley 20G21FD3P4JA0NNNNN PowerFlex 525 Variable Frequency Drive (VFD)

2. Product Introduction

The Allen Bradley 20G21FD3P4JA0NNNNN is a mid-power PowerFlex 525 VFD rated for 15HP, engineered to pair seamlessly with Allen Bradley Miniature Circuit Breaker for safe, precise industrial motor control.

3. Product Description

The Allen Bradley 20G21FD3P4JA0NNNNN is a high-performance model in the PowerFlex 525 series, tailored for mid-scale industrial automation with a 15HP (11kW) output capacity and 480V AC 3-phase input. This VFD is optimized to work in tandem with Allen Bradley Miniature Circuit Breaker, forming a integrated safety and control solution that balances efficiency, reliability, and protection for medium-duty applications.

Constructed with industrial resilience in mind, the drive features a standard IP20 (NEMA/UL Type 1) enclosure, with optional IP54 ratings to adapt to dusty workshops, humid processing facilities, and general industrial environments. It incorporates flexible control modes—sensorless vector, V/Hz, and optional closed-loop vector—enabling precise speed and torque regulation that reduces energy consumption by up to 35% compared to conventional motor control methods. The compact footprint (25.4×17.8×30.5cm) offers excellent power density, making it ideal for control cabinet installations where space efficiency is critical, while rugged internal components ensure 24/7 continuous-duty operation.

A key safety enhancement is its seamless integration with Allen Bradley Miniature Circuit Breaker, which provides rapid fault interruption (up to 15kA) to shield the VFD, motor, and electrical infrastructure from overloads, short circuits, and voltage irregularities. Complementing this, the drive includes built-in protections: overcurrent, overvoltage, undervoltage, thermal overload, ground fault detection, motor stall prevention, and phase loss protection—creating a dual-layer safety barrier that minimizes downtime and equipment damage. It operates reliably within a temperature range of -10°C to 65°C (with derating up to 75°C) and withstands industrial vibration and temperature fluctuations.

For integration flexibility, the 20G21FD3P4JA0NNNNN offers 12 digital inputs, 6 analog inputs, 6 digital outputs, and 4 analog outputs, facilitating easy connection to PLCs, HMIs, and industrial sensors. Standard communication modules (EtherNet/IP, Modbus RTU, DeviceNet) enable real-time data exchange and remote monitoring, supporting centralized control and predictive maintenance. Fully compliant with UL, CE, IEC, and RoHS standards, it meets global safety and environmental requirements. The user-friendly design includes pluggable terminal blocks, parameter cloning via USB, an intuitive LCD display, and self-diagnostic LEDs, simplifying setup, programming, and troubleshooting.
