Shizuki Electric RG-2 3-Phase Power Capacitor RG46B257UBJTA

The Shizuki Electric RG-2 series capacitor is a high-performance, dry-type power factor correction device designed for industrial and commercial electrical systems. This 3-phase unit, model RG46B257UBJTA, operates at 460V and 60Hz with a capacitance of 250μF, making it ideal for improving power efficiency by reducing reactive power in motors, transformers, and other inductive loads. Commonly used in manufacturing plants, power distribution networks, and oil/gas facilities to minimize energy losses, enhance voltage stability, and comply with utility regulations. Key features include a delta connection configuration, built-in safety device for overpressure protection, and robust construction for reliable operation in harsh environments. Advantages over similar products include Shizuki's reputation for high reliability, low dielectric loss, and long service life (up to 100,000 hours), often outperforming generic capacitors in terms of thermal stability and minimal maintenance needs. Drawbacks may include higher initial cost compared to basic models and the need for proper sizing to avoid resonance issues. This unit, manufactured in 2020, appears unused and in open-box condition, offering excellent value for upgrades or spares in power systems.
