FAQs
The ER4P-600N3PR is designed for typical panel board and switchgear mounting. Ensure proper back-panel support and adequate clearance for the pistol handle operation. It should be secured to a rigid frame, with appropriate torque on mounting hardware, and integrated into the existing Bussmann series protection topology for dependable isolation during routine maintenance.
This model specifies a 600A amperage rating and a 600V voltage rating, with a NEMA 4P enclosure. Use it to isolate high-current feeders in distribution panels or switchgear assemblies. Do not exceed the 600A/600V limits, and follow lockout-tagout procedures during disengagement to maintain safety.
Yes. The ER4P-600N3PR features a NEMA 4P enclosure suitable for outdoor and damp environments. CE marking further supports regulatory compliance in international markets. Ensure installation in a location with adequate drainage and environmental controls to maximize service life.
The product is CE marked and rated NEMA 4P, indicating robust protection for outdoor and industrial settings. It is non-fused with a pistol handle, aligning with common safety and operation standards in electrical protection and circuit control applications.
The non-fused design reduces fuse maintenance and inventory, lowering ongoing maintenance costs. Regular mechanical inspections of the pistol handle and enclosure are recommended, along with routine lubrication of moving parts. The result is improved uptime, faster maintenance cycles, and a favorable total cost of ownership in panels and switchgear installations.
