Quick Summary

The Eaton ER12-16N3PB Enclosed Rotary Disconnect Switch isolates power safely for industrial panels up to 600 V. When servicing equipment, unpredictable outages and startup surges threaten uptime; a robust disconnect minimizes risk. CE marking confirms compliance, while NEMA 12 enclosure protects against dust and moisture; the 600 V rating supports broad industrial use. With compact dimensions and pistol-grip handling, it installs easily in confined spaces and during routine maintenance. This unit's CE and NEMA ratings translate to reduced downtime, simpler regulatory alignment, and measurable cost savings for maintenance programs. Designed for reliability in continuous-duty environments, it supports scalable panel designs and easy sourcing through Eaton's Bussmann catalogs.

Special features
Non-fused, Pistol handle
Feature: Enclosed, non-fused design provides safe isolation without inadvertent fuse operation, enhancing personnel safety during maintenance and startup checks in panel assemblies. Business Impact: This topology reduces arc flash exposure, simplifies safety documentation, lowers ongoing maintenance costs due to fewer fuse replacements, and improves spare part planning across multi-shift operations. Application: Ideal for control panels and machine boundaries in manufacturing facilities where reliable isolation is essential, including high-cycle packaging lines and automated assembly cells. Feature: Pistol-handle operation for non-fused disconnects enables intuitive, one-hand energization or de-energization even in tight panel cavities. Business Impact: Fast, one-hand operation minimizes downtime during panel servicing and testing, reduces operator fatigue, and lowers the risk of mishandling energization. Application: Suitable for field service, robotics cells, and packaged equipment where quick, safe de-energization is required, such as material handling systems and injection-molding lines. Feature: 16A amperage, 600 V voltage rating with a NEMA 12 enclosure delivers robust protection against incidental contact and environmental ingress. Business Impact: Supports typical industrial loads while guarding against dust and moisture, improving equipment longevity, mean time between failures (MTBF), and overall uptime. Application: Common in conveyor lines, end-of-line packaging, and process equipment requiring robust, weather-resilient protection in manufacturing, food and beverage, and automotive facilities. Feature: CE marking and compatibility with Eaton Bussmann series catalogs streamline regulatory alignment and spare parts planning. Business Impact: Enables regulatory compliance across EU markets, simplifies procurement through familiar catalogs, reduces lead times, and improves part compatibility across protection devices in a given control system. Application: New builds or upgrades in facilities using Bussmann protection products, with easier stocking, consistent protection strategy, and scalable panel designs. Feature: Compact dimensions and lightweight profile with easy mounting facilitate flexible panel layouts. Business Impact: Simplifies panel layout, reduces installation time, and allows retrofits in tight electrical enclosures while maintaining operator access and safety clearances. Application: Panel builders and retrofit projects where space is at a premium and reliability is critical, including control cabinets in packaging, materials handling, and process automation.

FAQs

When installing the ER12-16N3PB, ensure proper panel clearance for the pistol handle, secure mounting within the enclosure, and correct wiring per the 16A rating. Verify that the cabinet supports a NEMA 12 environment and that insulation and shielding are adequate for 600 V systems. Use standard torque values on terminal screws and perform a functional test after mounting.
The device is rated for 16A with a 600 V voltage rating and a non-fused configuration. It utilizes a NEMA 12 enclosure for dust and moisture protection and features a pistol-handle operation for safe manual isolation. It is CE marked, aligning with European regulatory requirements and enabling broader international use.
Yes. The enclosure is designed for industrial control environments, offering quick isolation with a pistol-handle actuation, which minimizes maintenance downtime in robotic cells and automation panels. Its non-fused design reduces replacement parts and simplifies safety procedures, making it well-suited for automation lines that require reliable, repeatable disconnects.
The ER12-16N3PB is CE-marked, indicating conformity with European safety, health, and environmental protection standards. It also carries a NEMA 12 enclosure rating for dust and moisture protection. These certifications matter for regulatory compliance, Risk Assessment (RA) processes, and easier procurement in facilities that require standardized, EU-compliant electrical components.
Using a non-fused enclosed disconnect reduces fuse-related maintenance and replacement costs, lowers downtime during servicing, and simplifies spare-part planning within Bussmann-series ecosystems. The CE and NEMA 12 ratings help maintain regulatory alignment and extend panel life by protecting critical disconnects in dusty or damp environments.
