Eaton Specification Sheet - ER4P-030CF3PB
Enclosed rotary disconnect design provides reliable isolation with a compact footprint. This protects operators from live parts during maintenance, reducing arc-flash risk and improving safety metrics. It is well-suited for cabinet installations in industrial panels, streamlining commissioning and compliance checks. Three-pole operation ensures complete isolation of all three phases, preventing misconfiguration and accidental re-energization. The 30 A rating supports common motor and process loads while maintaining selectivity with compatible fuses. 600 V voltage rating with 50/60 Hz compatibility supports a wide range of equipment, from conveyors to machine tools. The Class CF fuse configuration coordinates protection with fast-acting fuses for short-circuit events, reducing downstream equipment damage. The NEMA 4P enclosure delivers weather and dust resistance suitable for indoor-outdoor locations and wash-down areas. This robustness helps maintain performance in harsh environments and lowers maintenance intervals. Compact dimensions of 9.84 in length, 8.91 in height, and 7.87 in width, coupled with a 2.5 lb weight, simplify mounting and retrofits in crowded panels. The selector handle enables quick, tool-free operation and minimizes training requirements for technicians. Compliance and compatibility: cULus listed and UL 98 considerations guide integration with Bussmann CF fuses and Eaton enclosure systems. This alignment supports streamlined procurement, consistent spares, and easier field servicing.

FAQs
ER4P-030CF3PB is designed for three-pole 600 V circuits with a 50/60 Hz supply. Its compact footprint fits standard panel cutouts, and the 9.84 in L × 8.91 in H × 7.87 in W enclosure allows mounting beside auxiliary devices. Ensure adequate clearance, proper wiring via Class CF fuse configuration, and alignment with cULus listed enclosure practices to maintain compliance and ease future maintenance.
The switch supports 600 V operation at 50/60 Hz with a 30 A rating, providing reliable isolation for common industrial loads. Its three-pole configuration ensures full three-phase isolation, while the CF fuse class coordinates protection with compatible fuses. This combination minimizes nuisance trips and supports safe commissioning in panel assemblies and machine controls.
Yes. The NEMA 4P enclosure delivers weather and dust resistance suitable for indoor-outdoor locations and wash-down areas. This rugged protection reduces environmental ingress, lowers maintenance frequency, and helps sustain performance in demanding manufacturing environments while meeting industry standards.
The product is cULus Listed, supporting North American electrical compliance. UL 98 certification is noted as a consideration path, with UL 98 in the certification queue. For procurement and maintenance planning, rely on the cULus listing for standard compliance, and verify UL 98 status with the supplier if UL 98 confirmation is required for specific projects.
The enclosed design and robust enclosure reduce exposure to dust and moisture, lowering routine maintenance and downtime. Its compact size, lightweight construction, and selector handle streamline installation and operator training, reducing labor costs. Standardized Class CF fuse configurations simplify spares provisioning, improving uptime and overall return on investment in panel upgrades.
