Overview

The WEG UCWT30D36 power factor correction capacitor is a high-efficiency, industrial-grade solution designed to improve power factor in three-phase electrical systems. Rated at 440V AC (50/60Hz), this capacitor delivers 30 kVAr of reactive power correction, optimizing energy efficiency and reducing utility costs in motor-driven applications. With a capacitance of 30 µF, the UCWT30D36 is engineered for direct connection in delta (Δ) configurations, providing balanced reactive power compensation where needed. Key specifications include a compact 45x94mm cylindrical design, weighing approximately 4.4 lbs, making it suitable for space-constrained installations. The capacitor features internal discharge resistors, ensuring terminal voltage drops to 1/10 of rated voltage within 30 seconds after power removal—enhancing safety during maintenance. Constructed with high-quality dielectric materials, it meets UL/CSA certification standards for reliability in harsh industrial environments. Typical applications include motor control centers, variable frequency drives (VFDs), and industrial machinery where inductive loads (motors, transformers) cause lagging power factors. By correcting power factor to near unity, the UCWT30D36 reduces apparent power demand, minimizes energy losses, and helps avoid utility penalties for poor power factor. Its Series F design aligns with WEG’s power factor correction portfolio, offering compatibility with WEG UCWT and BCW series capacitors. For systems requiring alternative voltages (e.g., 208V, 480V), WEG provides customizable solutions—contact WEG Automation for voltage-specific configurations. The UCWT30D36 is a drop-in replacement for legacy RCP-30/440V capacitors, ensuring seamless integration into existing installations. With a focus on durability and performance, this capacitor is ideal for continuous-duty operation in manufacturing, mining, and commercial facilities.
