Eaton 900TPHSR631S9 LV AutoVAR filter - NEMA 1 enclosure
Part Number: 900TPHSR631S9
Quick Summary
The Eaton LV AutoVAR filter provides reactive power support to stabilize voltage and improve power quality in industrial facilities. It helps address voltage sags, high harmonic distortion, and rising peak-demand charges that erode uptime and inflate energy costs. Engineered for reliability, it typically aligns with CE markings and SIL-rated configurations, while its indoor NEMA 1 enclosure enables straightforward installation in protected plant spaces. For procurement and engineering teams, the 400 KVAR rating on a 480 V 60 Hz system, combined with a rugged footprint and Eaton compatibility, delivers measurable value through improved efficiency, reduced wear on motors, and predictable maintenance planning.

FAQs
For indoor installations, ensure the space includes a protected environment suitable for a NEMA 1 enclosure. Confirm 480 V supply and 60 Hz system compatibility, and plan for adequate clearance for the 38 in L, 52 in W, 86 in H footprint and 2062 lb weight. Refer to the Eaton specification sheet for mounting guidance and required feeder connections.
Key specs include a 400 KVAR reactive power rating at 60 Hz with 480 V operation. The unit is designed to stabilize voltage, reduce harmonic distortion, and lower peak-demand charges in facilities with significant motor loads or variable-speed drives, such as pumps, fans, and conveyors.
Yes. The 900TPHSR631S9 is suited for retrofit projects where indoor, protected-environment installation is available. Its 380+ lb footprint and 86 in height require planning, but its large capacity (400 KVAR) enables meaningful power quality improvements without extensive downstream equipment changes. Verify bus, switching gear, and enclosure compatibility before installation.
The unit is designed for indoor use with a NEMA 1 enclosure. While CE marking and SIL-rated configurations are commonly considered in industrial deployments, confirm regional regulatory requirements with your compliance team and verify available certifications on the exact configuration you purchase. Always consult the official datasheet for current certification details.
ROI comes from reduced energy costs due to improved power factor and lower peak-demand charges, plus protection of motor-driven equipment from voltage stress. Maintenance is typically low due to solid-state reactive power control; rely on the datasheet and Eaton support for periodic checks of connections, enclosure integrity, and system health indicators.
