Square D CSN03 Heavy Duty Safety Switch 60A Copper/Aluminum Solid Neutral Assembly

Description

Features

• Engineered to scale flexibly with your distribution needs, this kit drops directly into both 30-amp and 60-amp Square DTM Heavy Duty Safety Switches (Series F). This cross-frame versatility simplifies on-site procurement and inventory tracking, ensuring facility teams always have the right component for different localized equipment layouts.
• Equipped with versatile, factory-installed dual-rated mechanical lugs, the assembly accepts up to 2 AWG copper or aluminum wiring. This material flexibility removes matching limitations in the field, allowing commercial electricians to save on material costs by landing existing feeder cables directly into the switch without requiring extra transition blocks.
• Designed with heavy-duty mechanical connection points, the assembly maintains a solid structural seat when torqued down from 35 to 50 lb-in depending on wire gauge. This rigorous mechanical security prevents wire loosening under constant machine vibrations, significantly lowering the risk of thermal runaway, localized tracking fires, and contact degradation.
• nstalling this solid neutral block upgrades your standard disconnect switch into an NEC-compliant service entrance device. It provides a dedicated, uninterrupted path for neutral current back to the main utility source, preventing dangerous floating neutral faults and safeguarding both upstream infrastructure and maintenance crews.
