Product Overview
The BSMJ0.4-14-3 is a self-healing low-voltage shunt power capacitor, utilizing metallized polypropylene film as the dielectric material. It features compact size, lightweight, and low energy loss, designed for reactive power compensation in low-voltage grids to improve power factor, reduce line losses, and stabilize voltage quality. Its modular structure facilitates easy installation and maintenance, suitable for industrial, commercial, and residential power systems.19
Key Features
With advanced metallized film technology, the BSMJ0.4-14-3 offers excellent self-healing capability, ensuring rapid recovery after overvoltage events. Built-in discharge resistors and safety mechanisms enhance operational safety, while semi-solid impregnation prevents oil leakage, aligning with environmental standards. The capacitor exhibits a low dissipation factor (<0.1%), minimal heat generation, and extended service life. It operates reliably in temperatures ranging from -25°C to +50°C, humidity ≤85%, and altitudes up to 2000m.268
Technical Specifications
Rated at 400V and 14kvar, the BSMJ0.4-14-3 has a total capacitance of 278.7μF and a nominal current of 20.2A. It withstands 1.75× rated voltage (10s) between terminals and 3000V (10s) between terminals and case. The product tolerates short-term overloads up to 1.1× rated voltage and 1.3× rated current, with residual voltage dropping to ≤75V within 3 minutes after power-off. Capacitance tolerance ranges from 0% to +10%.111722
Applications
Ideal for industries like petroleum, cement, and metallurgy, the BSMJ0.4-14-3 performs well in low-voltage systems with significant voltage fluctuations. It supports standalone or parallel configurations for flexible compensation solutions. Installation requires ≥30mm spacing for ventilation. Suitable for dry, well-ventilated indoor environments, avoiding direct sunlight and moisture exposure.3519
