Eaton Specification Sheet - ER4-16N3PR
Feature: Enclosed rotary disconnect switch design provides contained isolation for circuits within industrial panels. Business Impact: reduces arc flash exposure and improves personnel safety during maintenance and testing. Application: ideal for machine control panels and distributed motor control where reliable on/off isolation is required. Paragraph 2: Feature: Electrical rating of 16A at 600V defines the load range the ER4-16N3PR can safely interrupt. Business Impact: predictable performance, reduced fuse replacements, and lower downtime in equipment like conveyors and pumps. Application: general purpose control circuits in industrial automation environments. Paragraph 3: Feature: Non-fused operation with a pistol-style handle offers ergonomic actuation and simplifies lockout/tagout procedures. Business Impact: accelerates field servicing and reduces spare parts while maintaining safe isolation under NEMA 4 conditions. Application: panel-mounted disconnects for routine maintenance and process safety checks. Paragraph 4: Feature: CE marking confirms European safety compliance; NEMA 4 enclosure delivers weatherproofing for indoor or sheltered outdoor locations. Business Impact: supports cross-border projects and installation in harsher environments without redesign. Application: harsh-industrial settings and regulated facilities. Paragraph 5: Feature: Integration with the Eaton Bussmann series ecosystem, supported by catalogs and datasheets such as the Bussmann full line catalog no. 1007 and the ER4-16N3PR specification sheet. Business Impact: streamlined procurement, clear installation guidance, and consistent device compatibility. Application: procurement workflows and system design validations in automation projects.

FAQs
To install the ER4-16N3PR, mount the unit in a compatible enclosure using standard rotary disconnect mounting provisions, then wire per the Eaton specification sheet. Ensure the circuit is de-energized during installation and verify the 600 V rating is suitable for the system. The pistol-style handle provides ergonomic operation, and the non-fused design simplifies maintenance scheduling.
The ER4-16N3PR is rated for 16A at 600V with a NEMA 4 enclosure and a non-fused design. It features a pistol handle for easy actuation and carries CE marking for European compliance. This combination supports reliable isolation in general purpose control circuits within industrial environments and maintains safe operation under typical operating conditions.
Yes, the ER4-16N3PR uses a NEMA 4 enclosure, which provides weatherproof protection suitable for indoor and sheltered outdoor locations. The CE marking further supports regulatory compliance in many markets. While it is non-fused, it is designed for rugged industrial settings where dependable isolation and resilience are required.
The ER4-16N3PR is CE marked, indicating compliance with applicable European safety standards. This designation supports conformity assessment for many EU member states and helps streamline project approvals in European facilities. Always verify your specific application requirements and follow local electrical codes when designing control panels.
The non-fused, pistol-handle design reduces maintenance complexity and spare parts, lowering lifecycle costs. Its CE compliance and NEMA 4 enclosure enhance reliability in varied environments, reducing downtime from equipment isolation tasks. In practice, crews experience safer lockout/tagout procedures and quicker service intervals with predictable, standards-based performance.
