ABB TGN3323 - 100A, 240V, 3-Pole, Disconnect Switch

Introducing the ABB TGN3323, a high-performance disconnect switch designed for industrial and commercial environments where safe electrical isolation is non-negotiable. With a 100A rating at 240V and a true 3-pole design, this switch delivers dependable disconnection under load while fully supporting lockout/tagout procedures used by maintenance teams.

• 3-Pole isolation ensures all three phases are safely disconnected, preventing partial energization and giving you complete control during service.
• 100A, 240V capability covers common industrial power distribution for motors, conveyors, pumps, and other three-phase equipment.
• Lockout/Tagout ready design supports standard safety procedures, helping teams comply with maintenance isolation protocols and keep personnel protected.
• Durable, long-lasting performance built to withstand frequent operation and demanding environments found in facilities, plants, and commercial applications.
• Easy integration into existing panels and wiring schemes, enabling straightforward installation without major reconfigurations.
• Reliable disconnection under load ensures safe isolation even when circuits are energized or under load, reducing downtime and minimizing risk during maintenance.

Ideal use cases

• Maintenance shutdowns for motors, drives, pumps, and conveyors in manufacturing and processing facilities.
• Panel-level isolation during wiring upgrades, fault investigation, or routine servicing of electrical equipment.
• Safe, compliant isolation points within commercial electrical distribution networks that require clear, decisive disconnects.

Who should consider the ABB TGN3323

Facility managers, plant engineers, and industrial electricians who need a robust, 3-phase isolation solution for 100A circuits will find the TGN3323 to be a reliable cornerstone of safe electrical operations.

Why this solution stands out

Unlike generic switches, the ABB TGN3323 is purpose-built for reliable disconnection under load and seamless support of lockout/tagout practices. Its 3-pole design guarantees complete phase separation, enhancing worker safety during maintenance and reducing the potential for accidental re-energization. In demanding environments, this switch delivers consistent performance and longevity, helping you protect people and equipment while keeping downtime to a minimum.

Practical tips for deployment

• Plan for proper lockout/tagout devices and clear labeling at the disconnect point to maximize safety.
• Verify compatible enclosure size and mounting orientation to ensure accessible operation and secure installation.
• Match wiring gauges and terminations to the 100A rating to maintain electrical performance and safety margins.
