FAQs
Installation requires three‑phase 600 V supply compatibility, correct wiring to the unit's terminal blocks, and connection to the AutoVAR control system. Plan for space to accommodate a 78 in tall cabinet and ensure the 400 A circuit breaker is properly sized for fault current and motor starting loads. Follow UL 508A/UL 810 guidelines and CSA requirements for safe enclosure access and labeling. Use appropriate feeders, protective devices, and conductor sizes as per the facility’s electrical codes. A qualified electrician should complete commissioning with functional tests of reactive power support and protection circuits.
The unit provides 250 kVAR of reactive power at 600 V, enabling substantial power factor improvement and voltage stabilization under heavy motor loads. In typical plant conditions, you’ll see reduced voltage drop on feeders, lower current in supply cables, and potential energy cost savings through lower demand charges. The 400 A CB supports safe, scalable operation, and the three‑phase design ensures balanced reactive support across phases for consistent performance.
Yes. The 250TPCSR631M is designed for seamless integration with Eaton AutoVAR controls and standard switchgear assemblies. Its documented specifications—600 V rating, three‑phase configuration, and 250 kVAR capacity—align with common Eaton automation and protection schemes, facilitating straightforward retrofits or new installations. Properly sizing the control interface and protection devices ensures reliable closed‑loop VAR management and reduced commissioning risk.
The unit carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These indicate compliance with essential safety, performance, and electromagnetic compatibility standards, facilitating regulatory approvals, safer operation, and easier contractor acceptance in regulated environments such as manufacturing floors, data centers, and industrial automation facilities.
ROI is driven by improved power factor, reduced demand charges, and extended motor life due to steadier voltage profiles. Regular inspections of terminal connections, enclosure cleanliness, and protection devices are recommended. With UL/CSA certifications and Eaton support, maintenance intervals align with standard industrial practices, helping minimize unplanned downtime and optimize lifecycle costs for capital investments in power quality equipment.
