FAQs
The 300TPHSR631MW is a floor-mounted, low-voltage (600 V), three-phase switched capacitor bank designed to work with the AUTOVAR 600 family. It supports seamless integration due to its standard 600 V rating, 60 Hz operation, and compatible protection features. For retrofit projects, ensure clear space for the L-size NEMA 3R enclosure and verify existing protective devices match the unit's fuse protection requirements.
Key specs include a 300 kVAR rating with 6 x 50 kVAR steps, 288 A continuous current, 600 V voltage rating, and 60 Hz frequency. The unit is designed for three-phase, low-voltage applications and includes options for an integrated main breaker to simplify protection and commissioning.
Industries with heavy motor loads and variable demand—such as manufacturing, material handling, and process plants—benefit from improved power factor, reduced energy penalties, and extended motor life. The robust NEMA 3R enclosure and floor-mount design suit indoor plants and outdoor installations in harsh environments.
The unit carries UL Listed and CSA Certified marks, with a fuse-based protection scheme and a NEMA 3R enclosure. These certifications support regulatory compliance and safer operation in industrial facilities, while the enclosure protects internal components in demanding environments.
Maintenance is typically low, focused on periodic inspection of fuses and connections. ROI stems from improved power factor, energy savings, and reduced penalties. The integrated main breaker option further reduces downtime during maintenance and commissioning, contributing to faster project payback in automation-heavy facilities.
