Eaton 323NGB - 100A, 240V, 3-Pole, Disconnect Switch

Meet the Eaton 323NGB, a rugged 100A, 240V, 3-Pole Disconnect Switch engineered for reliable electrical isolation in demanding industrial and commercial environments. This switch is purpose-built to support safe lockout/tagout procedures while delivering dependable disconnection under load, helping facilities keep downtime to a minimum and workers protected during maintenance.

Key reasons to choose the 323NGB for your electrical panel and control gear:

• Three-pole, 100A at 240V provides complete isolation of all three phases in typical 3-phase systems, ensuring the circuit is fully de-energized before service.
• Secure lockout/tagout readiness supports standard safety workflows, making it easier to implement compliant maintenance practices and protect personnel.
• Reliable disconnection under load designed to perform consistently when a disconnect is required during active operation, reducing the risk of unexpected energization.
• Durable industrial construction built to withstand the rigors of busy facilities, with long-term durability that minimizes maintenance interruptions.
• Seamless integration into existing panel boards and switchgear, simplifying installation and ensuring a clean, organized electrical distribution setup.

Ideal applications include manufacturing lines, material handling systems, process equipment, pumps and conveyors, and HVAC/service panels where reliable isolation and safety compliance are critical. The 323NGB is well-suited for environments where quick, confident disconnection is needed to support routine maintenance or safety shutdowns without compromising system integrity.

What sets it apart is the combination of a straightforward, three-pole design with a robust 100A/240V rating, all backed by Eaton’s heritage of electrical reliability. Unlike smaller or single-pole solutions, the 323NGB ensures all phases are simultaneously isolated, providing a clear and unambiguous safe-off state for complex equipment and multi-phase circuits.

Practical tips to maximize value:

• Pair the 323NGB with disciplined lockout/tagout practices and clearly labeled safety signage to reinforce safe maintenance workflows.
• Plan wiring and mounting with your control panel layout in mind to streamline wiring harnesses and minimize space constraints.
• During installation, verify that the system is de-energized and that all three phases are fully isolated before service begins.
• Keep a preventive maintenance schedule to inspect actuator operation and connection integrity, ensuring long-term performance.
