Eaton Specification Sheet - ER4-600J3PR
The enclosed design of the ER4-600J3PR provides a secure, single-access disconnect point, protecting operators and downstream equipment from arc-flash exposure. Business impact: minimizes safety risk and helps meet lockout/tagout requirements across manufacturing cells. Application: ideal for factory automation, machine controls, and switchgear assemblies where reliable isolation is critical. Fuse type J with 600V/600A ratings offers coordinated protection that reduces fault propagation and downtime, keeping critical lines available for production. Application: power distribution in control panels and line-side disconnects, with easier fuse coordination. The pistol-style handle improves operator safety and reduces time to engage or disengage during maintenance, improving overall maintenance efficiency. Application: quick shutdowns during routine servicing and emergencies. The NEMA 4 enclosure adds environmental resilience, enabling use in wash-down or dusty environments without sacrificing safety or reliability. Application: outdoor installations and harsh indoor settings. CE marking and robust compatibility with Eaton Bussmann series protectors simplify global deployment for OEMs and panel builders, ensuring consistent compliance across regions.

FAQs
The ER4-600J3PR is designed as an enclosed rotary disconnect switch for Eaton Bussmann series configurations and fits standard electrical panels and switchgear where a single fuse-type J disconnect is required. It supports up to 600V and 600A circuits, with a pistol handle for quick, safe operation and straightforward integration into existing control architectures.
The device is rated for 600A and 600V, with a NEMA 4 enclosure for reliable protection in harsh environments. It uses fuse type J protection and carries CE marking for regulatory compliance. These ratings support safe isolation, fuse coordination, and long-term reliability in factory automation and power-distribution applications.
Yes. The NEMA 4 enclosure rating indicates suitability for outdoor or washdown environments where exposure to dust, water, or cleaning processes could affect equipment. This makes it appropriate for factory floors, outdoor enclosures, and harsh indoor settings, ensuring consistent performance and safety.
The ER4-600J3PR is CE marked, reflecting compliance with European electrical safety and performance standards. It also features a NEMA 4 enclosure rating, providing enclosure protection against dust and water. While UL/CSA listings aren’t specified in the data, the CE and NEMA 4 attributes support global deployment in compliant industrial environments.
The pistol-style handle simplifies safe operation, while fuse-type J protection and a rugged enclosure reduce maintenance time and potential downtime due to failed protections. These features contribute to improved uptime, safer lockout/tagout workflows, and a lower total cost of ownership in high-volume manufacturing or OEM panel builds.
