FAQs
ER4P-16N6SB is designed to fit within standard electrical panels that accommodate its 12 in depth, 12.25 in height, and 7.5 in width footprint. Being non-fused and selector-based simplifies wiring and operation, reducing commissioning time. When planning installation, verify enclosure clearance, orientation, and accessibility for safe operation and routine maintenance within existing Bussmann series protection schemes.
The device is rated for 16 amperes at 600 volts and employs a NEMA 4P enclosure. It is CE marked, confirming compliance with applicable European safety standards. These ratings support reliable isolation in industrial panels, conveyors, and machinery while maintaining safe operating conditions and regulatory alignment.
Yes. The NEMA 4P enclosure provides protection against rain, hose-directed water, and dust ingress, enabling use in outdoor or damp indoor installations. CE marking further supports regulatory compliance across markets. When selecting for outdoor use, ensure wiring methods and enclosure installation preserve the integrity of the switch’s protective rating.
The non-fused selector switch isolates power without requiring fuse replacements, reducing spare parts inventory and maintenance complexity. This design improves reliability and uptime in panel isolation tasks, simplifies operator training, and lowers total cost of ownership while delivering dependable power cut-off in routine and emergency shutdowns.
Choosing the Eaton Bussmann series enclosure provides a consistent protection ecosystem, facilitating part compatibility, streamlined procurement, and predictable lifecycle costs. The combination of robust enclosure, CE compliance, and standard electrical ratings supports faster project execution, easier spare parts management, and improved maintenance planning for industrial automation and electrical protection programs.
