Eaton Specification Sheet - ER4P-200J3PR
Enclosed rotary disconnect with a NEMA 4P enclosure delivers rugged protection against dust, moisture, and incidental contact. This design reduces field maintenance exposure and protects internal contacts, translating to longer service life and lower downtime. It is ideal for control panels, motor controllers, and service entrances in manufacturing environments where weatherproof isolation is required. Fuse type J compatibility with a 200A, 600V rating ensures the switch handles routine high-current switching without nuisance tripping, supporting coordinated protection within Eaton Bussmann series installations. The pistol handle enables safe, lockable operation, reducing the risk of accidental energization during maintenance and testing in MCCs and panel assemblies. With dimensions of 12 in depth, 12.25 in height, and 7.5 in width (weight 11.24 lb), installation is straightforward in standard enclosures. CE marking confirms compliance, while the rugged build promises a long service life and predictable lifecycle costs in harsh facilities.

FAQs
Begin with a suitable enclosure that accommodates a 12 in depth, 7.5 in width, and 12.25 in height unit. Ensure proper clearance for wiring and access to the pistol handle. Connect per 600 V, 200 A ratings using appropriate lugs and fuse-type J protection. Secure the device to the panel mounting provisions and verify CE compliance and NEMA 4P sealing before energizing.
The 200A rating specifies the maximum continuous current the switch is designed to interrupt safely, while the 600V rating defines the maximum operating voltage for the circuit. Together they guide safe isolation in electrical protection schemes, ensuring compatibility with typical motor control centers and high-current control panels in industrial environments.
Yes. The ER4P-200J3PR is designed as part of Eaton’s Bussmann series protection family, featuring fuse-type J compatibility. This alignment simplifies protection coordination, simplifies parts planning, and supports consistent performance when pairing the switch with Bussmann fuses and protection devices in a standard electrical protection strategy.
This enclosed rotary disconnect is ideal for control panels, motor control centers, service entrances, and outdoor or harsh-environment installations where reliable circuit isolation is required. Its NEMA 4P enclosure and CE marking make it suitable for indoor facilities and weather-protected outdoor areas, helping maintain safe maintenance windows and quick asset isolation when needed.
The combination of a rugged enclosure, pistol-style handle, and fuse-type J protection fosters reliable operation with minimal maintenance. Its CE and NEMA 4P ratings support long service life in challenging environments, reducing downtime and maintenance costs. Over the equipment lifecycle, this translates to improved uptime, safer servicing, and predictable budgeting for electrical protection.
