FAQs
Plan for floor mounting with a footprint compatible to the L-size enclosure (approximately 29 in long, 41.3 in wide, 80 in high). Ensure adequate clearance for service access, proper wiring to the integrated main breaker, and fuse protection as specified. The unit weighs about 952 lb, so use appropriate lifting facilities and anchoring per local codes.
The 300 kVAR switched capacitor bank provides reactive power support to raise power factor, reducing current for the same real load. Expect lower utility penalties, improved voltage stability, and potential energy cost savings, especially during peak loading or with motor-heavy equipment operating at 240V three-phase.
Best suited for low-voltage facilities with medium-to-large three-phase loads, such as motors, pumps, compressors, and assembly lines where power factor penalties or voltage regulation are a concern. It pairs well with AUTOVAR 600 deployments for scalable VAR management and lifecycle optimization.
The unit is UL Listed and CSA Certified, signaling safety compliance and reliability in industrial environments. Protective features include fused protection and an integrated main breaker, while the NEMA 1 enclosure and floor-mount design contribute to rugged reliability and ease of maintenance.
Warranty terms follow Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. For service, leverage the integrated main breaker and standard protection features to simplify preventive maintenance and coordinate with Eaton support for replacement parts and certified technicians.
