Safety Switch · 100A 2-Pole 240V · Fusible with Neutral NEMA 1 · Eaton CDG223NGB

What this product is for

This Eaton general duty safety switch provides a local disconnecting means for 240V circuits in commercial, institutional, and light industrial installations. It is a 2-pole, 3-wire fusible switch with neutral for indoor use.

Use for

Use for equipment isolation, serviceable disconnect locations, and branch or feeder circuits where a 100A fusible disconnect is specified. Typical applications include HVAC equipment, distribution points, and machinery disconnects in dry indoor areas.

Avoid for

Avoid using this switch outdoors or in washdown areas because it is a NEMA 1 indoor enclosure. Do not use where a non-fusible switch, higher short-circuit protection scheme, or service entrance rating is required without confirming the exact installation requirements and accessories.

Best for

Best for electricians and contractors needing a standard indoor 100A disconnect with fuse provision and a neutral. It suits projects where a general duty switch is acceptable and wall space is limited.

Installed in

Typically installed surface-mounted in electrical rooms, utility spaces, mechanical rooms, and indoor service areas. Enclosure size is approximately 18.8 in H x 9.1 in W x 7.4 in D (478 x 232 x 188 mm), so verify working clearance and conduit entry layout before ordering.

Why this product exists

This switch provides a code-oriented visible means of disconnect and overcurrent protection through cartridge fuses. The neutral makes it suitable for 3-wire applications where the circuit design requires it.

Compared with similar products

Compared with a non-fusible safety switch, this model accepts Class H cartridge fuses for added overcurrent protection. Compared with heavy duty switches, a general duty model is typically selected for standard commercial indoor applications where enclosure and switching demands are less severe. Confirm fuse type, horsepower rating, and local code requirements for the connected load.
