FAQs
The Eaton 125MCSR6313 AutoVAR 300 is designed for wall mounting in 600 V three-phase circuits. Begin by verifying clearances, mounting to a sturdy wall surface, and ensuring space for electrical connections. Use the optional molded-case circuit breaker (65 kAIC @ 480/600 V) for enhanced protection, and confirm compatibility with existing switchgear before energizing. Follow vendor installation sheets and local codes for a compliant retrofit.
Key specs include 120 A amperage rating, 600 V voltage rating, 125 kVAR total, and 5 x 25 kVAR step configuration. The unit is three-phase and wall-mounted with a J frame. Optional MCCB provides 65 kAIC protection. These figures inform your PF correction strategy, ensuring the bank matches your load profile while meeting short-circuit and safety requirements.
Yes, the AutoVAR 300 variant offers NEMA 3R weatherproofing for suitable outdoor or exposed locations. When selecting for harsh environments, rely on the weatherproof enclosure to protect capacitor banks from dust, moisture, and temperature variations. If outdoor exposure is a concern, coordinate with Eaton to confirm environmental ratings and any additional protective measures.
The 125MCSR6313 carries UL Listed, CSA Certified, and IEEE 18 compatibility, with UL 508A supporting industrial control equipment safety. These certifications help verify electrical safety, reliability, and adherence to standards critical for regulated industries, audits, and procurement approvals. They also streamline supplier qualification and reduce risk in compliance-heavy projects.
