FAQs
Plan for a panel cutout and mounting dimensions that accommodate a 10.4 in depth, 7.2 in width, and 6.7 in height footprint. Wire the four poles per schematic, tighten terminals to manufacturer torque specs, and maintain proper clearance for cooling and maintenance access. Use compatible Eaton accessories if required.
The switch provides a 25A amperage rating with a maximum HP of 7.5/7.5/15/20 hp across 208/240/480/600 V, and a voltage rating of 600 V. This makes it suitable for direct-mount motor control in indoor panels and reduces the need for additional external disconnects on mid-size motors.
Yes. It features a NEMA 1 painted steel enclosure designed for indoor service, complemented by UL Listed and CSA Certified safety assurances. Ensure the panel enclosure and wiring practices meet local electrical codes and that the installation location provides the appropriate environmental protection.
The unit is UL Listed and CSA Certified, providing independent safety validation and simplifying supplier qualifications. These certifications support regulatory compliance, streamline procurement, and reduce risk in panel assembly for NFPA 70/NEC-based installations and audits.
With a rugged painted steel enclosure and a one-year warranty (18 months from shipment), maintenance downtime is minimized due to fewer external components and simpler isolation. The compact footprint, ease of installation, and reliable safety isolation translate to faster panel commissioning, reduced labor costs, and improved overall uptime for motor-driven equipment.
