1. Product Name

Allen Bradley 20F14NC140JN0NNNNN PowerFlex 755 Variable Frequency Drive (VFD)

2. Product Introduction

The Allen Bradley 20F14NC140JN0NNNNN is a high-power PowerFlex 755 VFD, engineered for heavy-duty industrial motor control. It features seamless compatibility with Allen Bradley Miniature Circuit Breaker, delivering robust electrical safety and efficiency.

3. Product Description

The Allen Bradley 20F14NC140JN0NNNNN is a flagship model from the PowerFlex 755 series, designed to handle heavy-duty industrial motor control applications with a 100HP (75kW) output capacity and 480V AC 3-phase input. This drive stands out for its optimized integration with Allen Bradley Miniature Circuit Breaker, creating a synergistic safety system that safeguards critical automation infrastructure.

Built for industrial resilience, the drive boasts an IP21 (NEMA/UL Type 1) enclosure with optional IP54 rating for harsh environments, making it suitable for factory floors, processing plants, and heavy-industry facilities. It incorporates advanced control technologies—including vector control, torque regulation, and dynamic braking—enabling precise speed and load management for high-power motors, reducing energy consumption by up to 30% compared to direct-on-line starters. The compact design (35.6×25.4×40.6cm) maximizes control cabinet space, while industrial-grade components ensure reliability in 24/7 continuous-duty operations.

A key safety advantage is its seamless compatibility with Allen Bradley Miniature Circuit Breaker, which provides rapid fault interruption (up to 10kA) to protect the drive, motor, and electrical network from overloads, short circuits, and phase imbalances. Complementing this, the drive integrates comprehensive built-in protections: overcurrent, overvoltage, undervoltage, thermal overload, ground fault, and motor stall protection—forming a dual-layer safety shield that minimizes downtime and maintenance costs. Operating within a temperature range of 0°C to 50°C (derating up to 60°C), it withstands dust, vibration, and temperature fluctuations common in industrial settings.

For integration flexibility, the 20F14NC140JN0NNNNN offers 16 digital inputs, 6 analog inputs, 8 digital outputs, and 2 analog outputs, supporting easy connection to PLCs, HMIs, and sensors. Standard communication modules (EtherNet/IP, DeviceNet) enable real-time data exchange and remote monitoring in connected industrial networks, facilitating centralized control and predictive maintenance. Compliant with UL, CE, IEC, and RoHS standards, it meets global safety and environmental requirements for international deployments. The user-friendly design includes a backlit LCD keypad, parameter cloning, and self-diagnostic tools, simplifying setup, programming, and troubleshooting for maintenance teams.
