Eaton Specification Sheet - NST1018F D30361
Feature → Business Impact → Application: The NST1018F is a fused disconnect switch rated at 30A for 600 Vac circuits, delivering a reliable means to interrupt power and protect downstream equipment. This translates to safer startup/shutdown sequences and reduced risk of arc flash events, particularly in machine controls and panel assemblies. Application: ideal for industrial control panels and remote machinery where quick, compliant isolation is required. Feature → Business Impact → Application: Krydon fiberglass-reinforced polyester enclosure offers excellent chemical resistance and corrosion resistance while remaining lighter than metal alternatives; this reduces maintenance costs and eases installation in damp or dusty environments. Application: suitable for non-hazardous locations in manufacturing floors and assembly lines. Feature → Business Impact → Application: NEMA ratings 3, 12, and 4X provide rugged enclosure protection against dust, moisture, and modest corrosion, improving uptime in ordinary locations and ensuring long service life. Application: supports equipment enclosures in warehouses and process areas. Feature → Business Impact → Application: compact footprint with precise dimensions (11.41 in L, 19.41 in H, 15.47 in W) and a 32.94 lb weight simplifies mounting and reduces panel redesign needs. Application: fits standard NST series cavities and existing Square D installations. Feature → Business Impact → Application: NEC/CEC compliance streamlines procurement and installation, promoting safer operations and audit-ready documentation. Application: essential for new builds and retrofits in regulated facilities. Feature → Business Impact → Application: 20 hp compatibility and 600 Vac capability enable integration with a wide range of motor loads and control circuits, supporting scalable automation projects. Application: suitable for equipment requiring reliable motor control isolation and fuse protection with minimal aftermarket adjustments.

FAQs
Installers should verify the fuse type is fused as specified, mount the disconnect in a compatible NST panel opening, and connect the line and load conductors per NEC/CEC guidelines. Ensure secure enclosure sealing and proper torque on terminals to maintain electrical integrity and maintain the NEMA rating in ordinary locations.
Yes. This disconnect switch is rated for 600 Vac and 30 A, with a 20 hp capacity, making it suitable for motor loads and control circuits within standard industrial power distributions defined by NEC/CEC requirements.
The device features NEMA ratings 3, 12, and 4X, and is designed for NEC/CEC compliance in ordinary/non-hazardous locations, aligning with industry standards for safe panel isolation and power distribution.
Best suited for non-hazardous, ordinary location spaces such as machine control panels, process lines, and industrial control enclosures where a durable fused disconnect is required to safely isolate circuits and protect downstream equipment.
Maintenance benefits include longer service intervals due to corrosion-resistant Krydon material and a robust, fused design that minimizes fault propagation. ROI is realized through reduced downtime, simplified stocking of compatible NST components, and fewer panel reseals due to durable enclosures.
