Siemens JN-323 - 100A, 240V, 2-Pole, Fusible, Safety Switch

Siemens JN-323 – a rugged, fusible safety switch engineered for dependable on/off isolation and overcurrent protection in demanding industrial and commercial environments. With a 100A rating, 240V operation, and a compact 2-pole design, this unit is purpose-built for motor disconnects, panelboards, and branch circuit protection where space and serviceability matter.

What sets the JN-323 apart:

• Two-pole configuration ensures both hot lines are opened simultaneously, delivering a clean, safe disconnection and reducing arc exposure during maintenance or fault events.
• Fusible protection built into the switch provides immediate current interruption to protect downstream equipment and wiring from overloads or short circuits.
• 100A, 240V performance supports a wide range of medium-duty loads, from motors to control circuits, without requiring additional protection devices in many installation scenarios.
• Compact, maintainable design fits tight electrical rooms and panelboards, simplifying installation and future servicing while keeping critical circuitry clearly organized.

Ideal applications

• Motor disconnects in industrial machinery, processing lines, and HVAC equipment
• Panelboard protection where a dedicated disconnect with integrated overcurrent protection is desired
• Branch circuits that demand a compact, reliable isolation solution in commercial facilities
