Schneider Electric D323N Fusible Safety Switch

Schneider Electric's D323N is a 100 A, 240 V fusible general‑duty safety switch designed for indoor, three‑phase power distribution, serving as a hard disconnect that safely isolates downstream equipment such as motors, pumps, and conveyors while serving as a code‑compliant boundary in industrial or commercial enclosures. The unit is a 3‑pole, 4‑wire disconnect with a Type 1 enclosure that includes a neutral, and it accepts Class R fuses, offering reliable protection and a straightforward replacement path in routine maintenance or fault isolation tasks. On 240 V AC, it is rated to handle up to 15 horsepower for three‑phase motors and 100 A continuous current, with a single‑throw ON/OFF operation that enables quick shutdown of downstream circuits. Common applications include HVAC equipment, small machining or processing lines, and other indoor 3‑phase loads in residential or light commercial settings where a cost‑effective, durable safety switch is required.
