FAQs
The ER3R-060CF2PR is designed for standard two-pole mounting within typical electrical enclosures. Ensure proper panel cutouts to fit the 9.84 in depth, 7.87 in width, and 8.91 in height footprint, with space for the pistol handle operation. Follow the Eaton wiring diagram for line and load connections and maintain clear access for safe操作.
Key ratings include a 60A amperage, 600V voltage rating, and 50/60 Hz frequency. The unit features a NEMA 3R enclosure and is cULus Listed with UL 98 certification, with Class CF fuse configuration. When selecting, coordinate fault current, coordination with downstream devices, and ensure compatibility with protective devices used in the protection scheme.
Yes. The NEMA 3R enclosure is designed for outdoor and damp indoor environments, providing weather resistance and protection against incidental moisture. For outdoor installations, ensure proper conduit fittings and ventilation orientation, and maintain access for safe operation of the pistol-style handle during routine isolation tasks.
Class CF fuses offer fast fault clearance and selective protection, enabling a cleared upstream system to remain energized during a branch fault. This reduces downstream disruption and supports UL 98 coordination requirements. When designing protection schemes, pair CF fuses with properly rated upstream devices and appropriate fault-current calculations.
The rugged construction and standard certifications support longer service life and easier procurement, reducing maintenance downtime and spare-parts variety. As a common disconnect switch in industrial panels, it simplifies stocking and maintenance planning, improving uptime and overall return on investment through predictable performance and easier audits.
