Yes. The unit’s wall-mounted 3R enclosure and 240V three-phase design make it compatible with many retrofit projects. Its compact footprint and standardized certifications simplify integration with existing panels, while the 100 kvar rating provides substantial PF correction without overloading downstream equipment. Ensure panel compatibility and consult a qualified electrician for wiring and protection sizing.
The 100MCSR231MW carries UL 508A for industrial control equipment, UL 810 for electrical equipment in enclosures, and CSA C22.2 No. 190. IEEE Std. 18 compliance is noted for capacitor bank reliability. These certifications support safe operation, thermal performance, and electrical reliability in industrial settings, helping you meet plant safety and performance codes.
Reactive power correction reduces visible energy losses and improves voltage regulation, which can lower utility penalties and improve equipment efficiency. ROI varies with load profile and runtime, but facilities with sizable reactive power demand typically realize meaningful energy cost reductions within months to a few years, supported by proper PF monitoring and commissioning measurements.
