FAQs
The 300TPHSR431M is designed for 480 V three-phase systems operating at 60 Hz and delivers 361 A of current with a total 300 kVAR capacity. Its footprint (40 in L x 48 in W x 86 in H) and weight (880 lb) should be accounted for in floor mounting plans. The unit includes a main breaker and fuses for safe startup and straightforward integration with conventional switchgear or panels.
This capacitor bank provides six steps of 50 kvar each, totaling 300 kvar. The staged approach allows precise reactive power correction aligned to load profiles, reducing voltage drop during peak demand and supporting constancy in power factor. The 361A amperage rating at 480 V confirms the device’s capability to handle typical industrial motor starts and process loads.
The product is UL Listed and CSA Certified, confirming compliance with rigorous electrical safety and performance standards for industrial power equipment. These certifications support regulatory acceptance, safer installations, and easier procurement for facilities subject to electrical compliance requirements.
By delivering targeted reactive power correction, the AutoVAR 600 reduces reactive power draw from the grid, improving the overall power factor. This leads to lower demand charges and penalties from utilities, better transformer efficiency, and reduced motor stress due to voltage stability. The heavy-duty capacitor cells help maintain performance under demanding operating conditions.
Warranty coverage follows Eaton’s policy: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This provides post-installation protection against manufacturing defects and support for service and maintenance activities, including component inspection and replacement if needed within the warranty period.
