Eaton Specification Sheet - ER12-600N3PB
Feature → Business Impact → Application: The enclosed, non-fused rotary disconnect with a pistol handle delivers safe isolation during maintenance, reducing arc-flash exposure and empowering technicians to work quickly and confidently in busy panels. This translates into shorter downtime and safer turnarounds in machine control rooms that manage conveyors and packaging lines. Application: ideal for OEMs optimizing production lines with high-current loads. Feature: 600 V and 600 A ratings support heavy loads with fewer devices to stock, cutting wiring complexity and improving panel reliability. This simplifies power distribution in metalworking, plastics, and process facilities. Application: control cabinets and switchgear assemblies. Feature: CE marking and NEMA 12 enclosure provide indoor durability and regulatory alignment, reducing field failures and compliance risk. Application: industrial environments where moisture, dust, and routine cleaning are present. Feature: Dimensions (47.5 in L x 36 in W x 12.75 in H) and weight (19 lb) enable straightforward retrofits and easier handling during installation. Application: retrofit programs and greenfield projects with space constraints. Feature: Non-fused construction lowers spare-parts inventory and maintenance complexity, while the pistol handle speeds operator action and minimizes ergonomic strain. Application: field service, commissioning, and routine safety checks.

FAQs
The ER12-600N3PB is designed for retrofit and new-install use with a 47.5 in depth, 36 in width, and 12.75 in height footprint. Ensure adequate clearance for the pistol handle and motorized or manual operation, verify NEMA 12 enclosure suitability for indoor environments, and confirm CE compliance with your local electrical codes. Mounting hardware and panel cutouts should align with the catalog dimensions; consult Eaton documentation for recommended panel configurations.
This unit is rated for 600 A and 600 V, non-fused, with a NEMA 12 enclosure. It is intended to safely isolate high-current loads in electrical distribution panels, machine control cabinets, and power distribution centers. For critical operations, verify short-circuit current ratings and coordination with downstream protection devices to ensure safe disconnection under fault conditions.
Yes. The ER12-600N3PB is designed for rugged indoor installations such as machine control cabinets and process equipment panels. Its enclosed, non-fused design with a pistol handle enables rapid isolation during maintenance, while the 600 A / 600 V rating supports high-demand line flows typical in manufacturing environments.
The unit is CE Marked and features a NEMA 12 enclosure, reflecting compliance with essential safety and indoor-use standards. CE marking signals conformity with European product safety and EMC requirements, while NEMA 12 ensures protection against dust, falling moisture, and light splashing in indoor installations—important factors for regulatory readiness and risk mitigation.
The non-fused design reduces spare parts and maintenance complexity, while the pistol handle enables faster, safer manual operation. Durability and CE/NEMA compliance minimize downtime, reduce rework, and extend service intervals. Over time, operators experience lower total cost of ownership due to improved reliability, quicker maintenance, and better protection of critical equipment.
