Eaton Specification Sheet - 16528-3
Three-pole design delivers 840 A at 600 Vac/600 Vdc, enabling high-load distribution in compact panels. This architectural efficiency translates to faster assembly in manufacturing environments and more usable space within control cabinets, where every inch of panel real estate counts. The molded thermoplastic housing provides a lightweight, durable footprint that fits tight enclosures and resists impact during routine maintenance. UL 94-V0 flammability rating and RoHS compliance deliver safety and regulatory assurance for panel builders, OEMs, and systems integrators. The combination of flame resistance and restricted hazardous substances supports risk mitigation in hazardous environments and simplifies supplier qualification during audits. For additional certifications or assurances, Eaton catalogs and datasheets provide installation guidance and traceability. With a 1x2x1 inch footprint and a weight of only 0.045 lb, installation complexity is minimized and panel density is improved, even in retrofits. The compact form factor also reduces shipping footprint and inventory footprint on the factory floor, lowering total cost of ownership over the product lifecycle. Designed for fast field retrofit, the block enables predictable terminations and straightforward wiring schemes in three-phase systems. A precise 3.5 lb-in torque specification helps ensure dependable connections without over-tightening, decreasing the risk of thermal cycling, loosening under vibration, or intermittent contacts. Engineers rely on this torque stability to maintain electrical integrity during daily operation and over long service intervals. Compatibility with standard control panels and mounting patterns simplifies procurement and BOM planning, while the UL 94-V0 and RoHS features align with modern manufacturing compliance goals. Together, these attributes support scalable power distribution across evolving automation architectures, delivering reliability, safety, and cost efficiency across the lifecycle.

FAQs
For installation, plan for the block's compact 1x2x1 inch footprint and ensure adequate clearance for safe top and bottom wiring access. Use 3.5 lb-in torque on terminations to achieve secure connections without over-tightening, and route conductors to minimize vibration exposure. Verify panel compatibility with three-phase wiring schemes and maintain compliance with RoHS and UL 94-V0 requirements during mounting.
The 840 A rating supports heavy feeder applications and dense power distribution in a single block, reducing the need for multiple modular units. The dual voltage capability (600 Vac and 600 Vdc) accommodates both AC and DC system sections common in modern automation. In practice, design the panel layout to manage heat dissipation and ensure proper torque, enclosure rating, and conductor sizing align with these high-current specifications.
Yes, the three-pole configuration is well-suited for distributing power across three-phase systems. UL 94-V0 flame rating and RoHS compliance support safe operation in industrial settings, while molded thermoplastic construction provides impact resistance in rugged environments. Ensure enclosure protection and proper mounting to withstand vibration and temperature fluctuations typical of harsh environments.
The block features UL 94-V0 flammability rating and RoHS compliance, which helps meet safety and environmental requirements in many regions. While additional certifications are listed as available from the manufacturer, these two provide strong baseline assurances for panel builders and OEMs. RoHS compliance simplifies supplier qualification and can streamline regulatory reporting for electronics assemblies.
Maximize ROI by leveraging its torque specification to ensure stable terminations and minimize intermittent contacts, which reduces rework. Favor a compact footprint to simplify panel redesigns and upgrades, lowering installation time. Maintain documentation with the catalog number for easy sourcing, and periodically verify RoHS and UL 94-V0 compliance during audits to avoid procurement delays.
