Fusible safety switch · 100A 240V 2-pole NEMA 3R with neutral · Eaton DG223NRB
What this product is for
This general duty fusible safety switch provides a visible means of disconnect and overcurrent protection when used with the correct Class H fuses. It is built for 240V single-phase circuits that need a 2-pole disconnect with a factory-installed neutral in a NEMA 3R enclosure.
Use for
Use for outdoor or indoor installations where a weather-resistant disconnect is needed for feeders, service entrance equipment where permitted, pumps, compressors, rooftop equipment, and other commercial or light industrial loads. It is commonly selected when a neutral termination is required in the enclosure.
Avoid for
Avoid for applications that require a heavy duty safety switch, higher short-circuit performance than the fuse system provides, or voltage and pole configurations outside this 240V 2-pole design. Do not use without verifying fuse class, conductor range, enclosure suitability, and local code requirements.
Best for
Best for electricians and contractors needing a 100A outdoor-rated fusible disconnect with neutral for general duty commercial and industrial branch or feeder isolation. It suits jobs where a straightforward surface-mounted disconnect is preferred.
Installed in
Typically installed on exterior walls, service areas, mechanical spaces, warehouses, agricultural buildings, and light industrial facilities. The NEMA 3R enclosure is intended for rain-resistant outdoor mounting.
Why this product exists
This switch gives installers a code-accepted means to isolate equipment and add fuse protection in one enclosure. The included neutral helps where a neutral conductor must terminate or pass through with the disconnect assembly.
Compared with similar products
Compared with a non-fusible disconnect, this model adds overcurrent protection through field-installed Class H fuses. Compared with heavy duty safety switches, Eaton's DG series is a general duty option for applications that do not require the heavier construction and switching endurance of a heavy duty unit.
