Eaton Fusible AC Disconnect, 100A, 240V – DG223NRB

Product Overview

The Eaton DG223NRB is a 100 A, 240 V general-duty fusible cartridge-fuse safety switch in a NEMA 3R painted galvanized steel enclosure.

Fusible with neutral means the switch accepts Class H cartridge fuses and includes a neutral — use it when overcurrent protection at the disconnect is required.

Best For

• Outdoor 100 A AC disconnect points: Where a lockable fusible cartridge-fuse switch is specified for equipment isolation.
• Fused outdoor disconnects: 100 A, 240 V points that need Class H cartridge fuses at the switch.

Key Features & Specifications

What You May Also Need

Usually required

• Correctly sized conductors and overcurrent protection for the load (provide fuses for fusible models; provide upstream protection for non-fusible models).
• Lockout/tagout hardware as required by the job.

May be required

• Disconnects & Breakers: Matching Eaton Type BR breakers or related disconnects for the same project.

Optional upgrades

• Enclosures, Electrical & Safety: Outdoor enclosures and related balance-of-system hardware.

Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.

Important Considerations

• Select fuse ampacity and type per the load and Eaton fuse tables. Eaton notes that maximum horsepower ratings apply only when dual-element fuses are used — this listing does not state a horsepower rating.
• Confirm wire sizing, grounding, and enclosure clearances with the installation instructions.
• General-duty switches are for lighter-duty residential and light commercial use. Confirm suitability for the application against Eaton documentation.
• Professional installation required. Follow Eaton instructions and the NEC.
