FAQs
The unit uses a compact 14 gauge steel frame with a powder-coated finish and weighs about 20 lb, enabling flexible mounting in commonly sized electrical rooms. It is enclosed in a NEMA 1, NEMA 3R housing suitable for indoor and outdoor use. Plan for 480 V supply and three-phase connections, and account for a non-fused protection scheme as configured by the system designer.
Catalog notes indicate to convert 240 V kVAR values for 208 V operation by multiplying the 240 V kVAR rating by 0.75. For this 8 kVAR bank, that corresponds to approximately 6 kVAR at 208 V, preserving the corrective effect while accommodating voltage variations in the site supply.
Yes. The 843PMURN employs an enclosure rated for indoor and outdoor environments (NEMA 1, NEMA 3R), and its powder-coated 14 gauge steel frame provides durable protection against weather and dust, making it suitable for outdoor or semi-exposed installations when properly mounted.
The unit is CSA Certified and UL Listed, signaling compliance with North American safety and performance standards. These certifications simplify procurement, regulatory approvals, and quality assurance, particularly for industrial facilities and data centers with strict supplier qualification requirements.
A one-year warranty from installation or 18 months from shipment helps cover early defects, while the robust powder-coated steel enclosure and non-fused design reduce maintenance time and upfront wiring requirements. Expect energy savings from improved power factor and reduced penalties, with a straightforward upgrade path for retrofit projects in motor-driven applications.
