FAQs
Plan for the 14 in depth and 36x36 in footprint, ensure adequate mechanical clearance, and verify wall-mount suitability. If upgrading from a smaller bank, confirm space for the 290 lb unit and wiring routes to accommodate the optional 65 kAIC MCCB. For outdoor or harsh environments, consider the NEMA 3R weatherproofing option and factory consultation for rating adjustments.
Key specs include a 216A amperage rating, 225 kVAR total, 600 V three-phase operation, and 5 x 45 kVAR stepping. The unit is wall-mounted with optional MCCB protection; dimensions are 14 in depth by 36 in height and width, and it weighs about 290 lb, enabling straightforward panel integration.
Yes, with the optional NEMA 3R weatherproofing and robust mounting on walls, the AutoVAR 300 is designed for moderate outdoor exposure and challenging indoor spaces. Proper enclosure selection and adherence to clearance and cooling requirements ensure reliable operation in fluctuating ambient conditions.
The unit carries UL Listed and CSA Certified labels, along with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications support safe installation in professional panels and compliance with industrial automation standards.
Automatic VAR control reduces manual switching, stabilizes voltage, and lowers utility demand charges, contributing to faster payback. With a one-year warranty from installation or 18 months from shipment, depending on which occurs first, maintenance needs are typically limited to periodic inspections and standard electrical panel upkeep.
