Eaton Specification Sheet - ER12-16N3PR
Non-fused design saves maintenance costs and streamlines replacements; it eliminates fuse handling, reducing failure points and arc exposure while simplifying spare parts inventory. This translates to shorter downtime during servicing and lower total cost of ownership for control panels in manufacturing environments. The pistol handle offers a secure grip and clear position indication, enabling quicker, safer line clearance during changeovers and improving lockout/tagout efficiency for maintenance staff. With a 600 V rating and 16 A current capacity, it accommodates typical industrial control circuits and motor disconnects found in conveyors and automation equipment, delivering reliable performance with straightforward installation. The NEMA 12 enclosure provides dust and light moisture protection for indoor environments, reducing environmental risk to sensitive components and supporting long-term durability. CE marking confirms compliance with European safety standards, aligning with broad procurement requirements and ensuring compatibility within the Eaton Bussmann series ecosystem for streamlined sourcing.

FAQs
ER12-16N3PR is designed for indoor control panels and switchgear with standard enclosure openings. It accommodates 600 V circuits up to 16 A in a non-fused configuration, simplifying wiring and reducing fuse management. The NEMA 12 rating provides protection against dust and light moisture, making it suitable for manufacturing floors, packaging lines, and machine control rooms.
The pistol-style handle provides a secure grip and a clear on/off indication, enabling faster isolation during lockout/tagout procedures. By avoiding fused components during operation, it reduces exposure to live parts and arc risks. Operators experience shorter changeover times and fewer errors, which translates into safer maintenance tasks and higher equipment availability.
Yes. The unit is CE marked and features a NEMA 12 enclosure, ensuring compliance with European safety standards and robust indoor protection. It integrates well with the Eaton Bussmann series ecosystem, supporting standard protection and circuit-control components and simplifying regulatory documentation during procurement.
Review the circuit load to confirm 16 A is sufficient and ensure appropriate upstream protection since the ER12-16N3PR is non-fused. Verify panel space and wiring accessibility for a clean retrofit, and confirm indoor placement aligns with the NEMA 12 rating. The CE marking helps streamline compliance documentation for international operations.
Switching to a non-fused disconnect reduces spare-part inventory and simplifies maintenance routines, cutting downtime during isolation tasks. The pistol handle and simplified wiring lower training requirements and operator error rates, delivering measurable productivity gains and improved equipment availability over the system lifecycle.
