Eaton DG326NRK – Frequently Asked Questions

1) What is this Eaton 600A general duty safety switch used for?
This 600-amp three-pole safety switch provides manual disconnect and overcurrent protection for industrial motors, lighting panels, and distribution equipment. The fusible design uses Class H cartridge fuses for reliable circuit protection.
2) What fuse types are compatible with this switch?
This switch accepts Class H cartridge fuses up to 600 amps. Class H fuses provide standard time-delay characteristics for motor starting loads. Verify fuse amperage matches your load requirements.
3) Can this NEMA 3R enclosure be installed outdoors?
Yes, the NEMA 3R rating allows outdoor installation. The painted galvanized steel construction resists corrosion from rain, sleet, and wind-blown dust. Mount in locations protected from direct water spray.
4) What does the neutral provision offer?
The four-wire configuration includes a solid neutral bar for connecting system neutrals. This allows switching of three-phase, four-wire systems while maintaining continuous neutral connection as required by code.
5) What voltage ratings apply to this switch?
This switch handles 240V systems as specified. Verify your system voltage matches the switch rating. Do not exceed rated voltage as this compromises safety and violates electrical codes.
6) Does this meet NEC requirements for motor disconnects?
Yes, when properly sized this switch meets NEC Article 430 motor disconnect requirements. The switch must be within sight of the motor and rated for motor horsepower. Consult local codes for specific installation requirements.
