FAQs
When installing the Eaton 9043PMURF, mount it in a suitable NEMA 1 or NEMA 3R enclosure with the C1 frame compatible mounting arrangement. Ensure correct wiring to a three-phase 480V supply, observe proper bus spacing and clearance for heat dissipation, and integrate the three fused circuits with 200,000 AIC capability. Refer to the Eaton specification sheet for detailed wiring diagrams and torque values.
The catalog notes specify that the 240V kVAR rating should be multiplied by 0.75 to estimate the kVAR value at 208V. For example, a 90 kVAR rating at 240V would correspond to approximately 67.5 kVAR at 208V. Use this adjustment when planning PF correction for systems that operate at 208V to avoid under- or over-correction.
The 9043PMURF is UL Listed and CSA Certified, reflecting compliance with recognized safety and performance standards. These certifications help meet procurement requirements and regulatory obligations, facilitate insurance and commissioning approvals, and provide confidence in safe operation, particularly in hazardous or mission-critical industrial environments.
The unit is available with NEMA 1 and NEMA 3R enclosure options, suitable for indoor and outdoor use. The cabinet uses a 14-gauge steel shell with a durable powder coat finish and accommodates the C1 frame size for compact installation. Weight is approximately 68 lb, allowing for straightforward mounting to existing bus ducts or panel assemblies with standard hardware.
Warranty coverage is Eaton Selling Policy 25-000, offering one year from installation or 18 months from shipment, whichever comes first. Maintenance considerations include inspecting neon indicator lights for fuse status, replacing three slotted-blade fuses as needed, and periodic enclosure cleaning. The design emphasizes reliability with a high AIC rating and straightforward fault indication to minimize downtime.
