Eaton Specification Sheet - ER4P-030CF3PR
Feature → Business Impact → Application: Enclosed construction with a NEMA 4P-rated enclosure delivers rugged, weather-resistant protection for outdoor or washdown environments, reducing dust ingress and water exposure. This enhances operator safety and equipment uptime, making the ER4P-030CF3PR ideal for packaging lines and food-processing facilities where reliable isolation is essential. Feature → Business Impact → Application: The Class CF fuse configuration provides precise short-circuit protection and selective coordination, reducing arc energy and enabling faster fault clearance. This lowers total cost of ownership across manufacturing lines, particularly where frequent startup/shutdown cycles occur. Feature → Business Impact → Application: Three-pole design with a selector handle simplifies wiring and disconnection sequences, enabling straightforward maintenance procedures and safe lockout-tagout. This is especially valuable in multi-axis automation cells and conveyor systems requiring predictable isolation points. Feature → Business Impact → Application: UL 98 certification and cULus compliance (listing status may vary by catalog) alongside 50/60 Hz operation ensures regulatory alignment and market access in North America. Customers can integrate the ER4P-030CF3PR with Bussmann CF fuses and existing protection schemes to meet safety standards. Feature → Business Impact → Application: Compact footprint (9.84 in L × 8.91 in H × 7.87 in W) and modest 2.5 lb weight enable easy mounting and retrofit into existing panels, reducing installation time and enabling scalable protection across facilities.

FAQs
The ER4P-030CF3PR is a three-pole enclosed rotary disconnect designed for 600 V, 30 A service with a Class CF fuse. It fits a NEMA 4P-rated enclosure and uses the selector handle for safe lockout procedures. Consider panel cutouts, mounting clearances, and wiring compatible with Bussmann CF fuses; the unit dimensions are 9.84 in (L) × 8.91 in (H) × 7.87 in (W) with a weight of 2.5 lb.
Yes. The ER4P-030CF3PR is specified for 50/60 Hz operation, making it suitable for standard North American AC control systems and equipment protection schemes that require reliable circuit isolation.
This model features UL 98 certification and cULus compliance (with catalog-specific listing status noted). The NEMA 4P enclosure rating provides environmental protection. These certifications matter because they validate safety, reliability, and regulatory alignment for industrial installations and help meet audit requirements.
The Class CF fuse configuration provides precise short-circuit protection and selective coordination, reducing arc energy and limiting fault impact. In practice, this translates to improved equipment protection, safer maintenance windows, and easier integration into existing protection schemes in machine and panel designs.
ER4P-030CF3PR is designed to accommodate Class CF fuses within a rugged NEMA 4P enclosure and selector handle. It supports straightforward wiring, three-pole isolation, and is compatible with Bussmann CF fuse families, enabling seamless upgrades to safety and protection without major panel redesigns.
