FAQs
The 250MCSR631M is a three-phase AutoVAR capacitor bank rated for 600V and is designed for straightforward integration into standard low-voltage distributions. It matches common control panel footprints, uses a wall-mount configuration, and aligns with UL 508A, CSA, UL 810, and IEEE 18 standards to simplify panel assembly and commissioning.
Expect tangible power factor improvement as reactive power is shifted from the grid to the capacitor bank, reducing line current and peak demand charges. Savings depend on load profile and baseline PF, but organizations typically realize payback through reduced utility penalties and improved motor efficiency with the 250 kvar capacity.
Yes. The three-phase, 600V AutoVAR design is well-suited for motor-driven loads common in HVAC, pumps, and conveyors. Its automatic switching maintains voltage balance under varying loads, ensuring stable operation and reduced voltage drop across critical equipment.
The product carries UL 508A for control panels, UL 810 for enclosures, CSA Std. C22.2 No. 190, and IEEE Std. 18, providing strong safety and performance benchmarks. These certifications support compliance with industry regulations and facilitate safer panel integration and audits.
Eaton provides specification sheets and installation documentation, aiding project planning and commissioning. ROI comes from energy savings and improved process stability; the up-front cost is offset by reduced energy charges and longer-term reliability, with the potential for scalable integration as loading grows.
