Eaton ER4P-030CC3PR Enclosed Rotary Disconnect - NEMA 4P
Part Number: ER4P-030CC3PR
Quick Summary
ER4P-030CC3PR is an enclosed rotary disconnect switch designed for commercial and industrial electrical protection in control panels. Maintenance teams often struggle with safe isolation in cramped control panels or outdoor enclosures, which can delay startups. CE Marked, UL 98, and cULus Pending certifications paired with a NEMA 4P rating ensure regulatory compliance and weather resistance. Designed for 600 V systems at 30 A in a three-pole format with a red pistol handle, it delivers reliable Class CC protection and reduces commissioning time, downtime, and field service visits. This combination supports safer lockout/tagout workflows and faster fault diagnosis when used in automation and power distribution applications.

Eaton Specification Sheet - ER4P-030CC3PR
Enclosed rotary disconnect with Class CC fuse configuration consolidates protection and isolation in a single rugged enclosure. This reduces wiring complexity and short-circuit propagation, delivering faster, safer startups in 600 V control circuits for industrial machinery and process lines. The pistol-style handle enhances ergonomic operation, minimizing operator fatigue during routine maintenance and switch operations. NEMA 4P-rated housing, along with CE/UL safety markings, provides reliable performance in wet or dusty environments, improving uptime and simplifying regulatory audits for outdoor switchgear and rugged equipment. Three-pole, 50/60 Hz operation ensures compatibility with standard three-phase power systems, enabling straightforward integration with existing Bussmann protection schemes and reducing panel retrofit risk. The compact footprint and color-coded red actuator support safer lockout/tagout workflows, improving maintenance accuracy and compliance. Finally, the 9.84 in depth, 8.91 in height, and 7.87 in width fit neatly into common panel depths, reducing enclosure fill and easing retrofits.

FAQs
To ensure compatibility, verify the panel depth and mounting footprint fit the 9.84 in depth by 7.87 in width, and confirm a three-pole 600 V circuit with a 30 A rating. Use the red pistol handle for clear operator status, and align the Class CC fuse configuration with the Bussmann protection scheme already installed in the panel. Ensure enclosure rating meets environmental requirements (NEMA 4P).
Class CC fuses are compact, fast-acting devices designed for defensible short-circuit interruption in medium-voltage circuits. In a 600 V system, this configuration provides selective coordination with downstream protection, reducing arc flash exposure and minimizing downtime while preserving equipment integrity. When paired with a three-pole disconnect, it enables coordinated protection across three-phase loads.
Yes. The NEMA 4P rating indicates protection against windblown dust and rain, hose-directed water, and corrosion in many outdoor and harsh indoor environments. Combined with CE and UL 98 listings (cULus pending), the device supports compliant, reliable operation in outdoor switchgear, process lines, and industrial equipment exposed to challenging weather or particulate exposure.
Key certifications include CE Marked and UL 98 with cULus Pending status. These marks support compliance with European and North American electrical safety standards, enabling risk mitigation during retrofits and new installations. The NEMA 4P enclosure further reinforces environmental protection requirements, helping with regulatory audits and plant safety programs.
Maintenance benefits arise from a clearly isolated circuit point, ergonomic pistol handle operation, and straightforward fuse replacement within Class CC configurations. These features reduce downtime during inspections and faults, lower maintenance labor costs, and shorten commissioning cycles. Over time, the robust enclosure rating and standardized Bussmann integration support faster retrofits and a clearer path to ROI through improved equipment availability.
