Eaton Specification Sheet - ER1-600N3PB
Non-fused enclosed design with a pistol handle provides safer manual operation and minimizes arc flash during switching, reducing the risk to technicians in tight control cabinet spaces. This translates to faster, safer maintenance windows and lower incident exposure, particularly in high-availability manufacturing lines where downtime is costly. The unit’s 600 V and 600 A ratings support main feeders and motor-control circuits without resorting to parallel devices, simplifying wiring and reducing installation time. NEMA 1 enclosure offers indoor protection against dust and incidental contact, enabling reliable operation in typical factory environments. CE Marked compliance ensures regulatory acceptance across European and other markets, helping engineers meet compliance timelines and reduce certification delays. Bussmann series compatibility and access to Eaton catalogs streamline specification and procurement for the broader protection system, supporting faster project delivery.

FAQs
To install the ER1-600N3PB, mount the unit inside a suitable control panel, ensure power is shut off, and secure the switch with the recommended mounting hardware. Connect the incoming and outgoing conductors to the appropriate terminals, verify the 600 V rating matches your circuit, and perform a final mechanical and electrical check before energizing. Refer to Eaton’s datasheet for torque specs and clearances. The pistol handle enables safe manual operation during maintenance once installed.
ER1-600N3PB is rated for 600 A and 600 V with a NEMA 1 enclosure. NEMA 1 indicates indoor, general-purpose protection against dust and incidental contact, suitable for clean environments like control panels and indoor switchgear. The non-fused design means the switch provides isolation without built-in fusing, requiring separate protection devices in the circuit. These ratings help determine compatibility with your feeders and motor-control circuits.
Yes. With a 600 A current rating and 600 V voltage rating, this enclosed rotary disconnect is appropriate for isolating motors and feeders in manufacturing and processing facilities. Its non-fused design reduces startup complexity, while the pistol handle supports safe operation for maintenance and service. The rugged indoor enclosure combined with CE Marked compliance makes it a practical choice for controlled indoor motor-control applications.
ER1-600N3PB is CE Marked, indicating conformity with European health, safety, and environmental requirements. The device also carries a NEMA 1 enclosure rating for indoor protection. These certifications support regulatory acceptance and safer integration into international control panels, service entrances, and maintenance workflows. Always verify local compliance requirements for your specific installation scope.
The non-fused, enclosed design with a pistol handle enables quick, safe isolation during maintenance, reducing downtime and exposure to arc or electrical hazards. Its high-current rating minimizes the need for multiple devices, simplifying wiring and spare-part inventories. In practice, this can shorten maintenance windows, improve technician safety, and provide more predictable uptime for critical manufacturing lines, delivering measurable total-cost-of-ownership benefits.
