FAQs
This floor-mounted unit uses a rugged NEMA 3R enclosure, supports a fused protection approach, and offers an integrated main breaker option. Ensure adequate clearances for service access, vibration control, and proper wiring to the low-voltage bus. Verify compatibility with AUTOVAR 600 systems and local seismic or environmental requirements before mounting.
Key specs include a 75 kVAR rating at 180A, 240V, 60 Hz, three-phase operation, and a 29 in depth, 80 in height, 41.3 in width footprint with a 584 lb weight. The device is designed for low-voltage applications with fuse protection and optional integrated main breaker for streamlined protection.
Yes, the unit is UL Listed and CSA Certified, providing recognized safety and compliance for industrial installations. This helps with project approvals, procurement audits, and ensures alignment with common regulatory and safety standards.
The 3 x 25 kVAR steps allow precise, staged reactive-power correction, reducing the risk of overcorrection and voltage flicker during load swings. This improves power factor gradually, minimizes harmonic stress on the network, and supports stable motor starting conditions for varied demand.
Warranty follows Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance focuses on connector integrity, enclosure cleanliness, and protection system checks; the integrated main breaker option simplifies periodic testing and safe operation.
