FAQs
The ER3R-600J3PR installs into standard electrical enclosures designed for Bussmann series disconnects. Use the pistol handle for operable isolation and ensure the wiring conforms to 600 V, 600 A ratings. Verify clearance and mounting hardware per the catalog guidelines, and connect fuse-type J links as required by your protection scheme. This design supports straightforward retrofits and minimizes panel modification while maintaining compliance with CE and NEMA 3R requirements.
Key specifications include a 600 A amperage rating and a 600 V voltage rating, with a NEMA 3R enclosure suitable for indoor and outdoor environments. The device uses fuse type J protection and a pistol handle for easy operation. Its 3R rating ensures protection against rain and other elements, supporting reliable performance in rugged industrial settings.
Yes. The ER3R-600J3PR is well-suited for motor control centers, switchgear, and other panel assemblies requiring safe isolation and reliable switching. Its 600 A/600 V ratings accommodate large motors and feeders, while the NEMA 3R enclosure provides weather-resistant protection, making it a versatile choice for both indoor and outdoor installations.
The ER3R-600J3PR is CE marked, indicating compliance with European safety standards. Its NEMA 3R enclosure confirms suitability for protected outdoor and indoor use. While UL or others are not specified in the data, the CE marking and NEMA 3R rating address common regulatory and environmental requirements for industrial equipment in many regions.
The enclosed design and fuse-type J with a pistol handle streamline maintenance and reduce downtime, as isolation points are clearly accessible and easy to operate. The robust 600 V/600 A rating supports fewer components in parallel, lowering parts costs. CE and NEMA 3R compliance also minimize commissioning risk, contributing to faster project timelines and predictable long-term ownership costs.
