Siemens TFP323 - 100A, 240V, 3-Pole, Fusible, Pullout Switch

Siemens TFP323 is a rugged 100A, 240V, 3-Pole Fusible Pullout Switch engineered to deliver dependable on/off isolation and overcurrent protection in demanding industrial and commercial environments. This compact, maintainable switch is purpose-built for reliable motor disconnects, panelboard feeds, and branch circuit protection where space and accessibility matter.

• Model: TFP323
• Amperage: 100A
• Voltage: 240V
• Poles: 3-Pole
• Fusible: Fusible design for protective switching

Why the TFP323 stands out

Unlike simple disconnects, the TFP323 integrates overcurrent protection with a tactile pullout mechanism that enables quick, safe fuse inspection and replacement. Its three-pole configuration ensures synchronized isolation of all phases, which is essential for three-phase motors and equipment. The fusible design adds an additional layer of protection, helping to limit fault currents and protect downstream devices without requiring separate protection modules.

Ideal use cases

• Motor disconnects on conveyors, pumps, fans, and compressors where a compact, maintainable disconnect is essential
• Panelboards and switchgear feeders needing reliable isolation and protection in limited-space installations
• Branch circuit protection in commercial or industrial installations where quick fuse access supports fast maintenance

What problems it solves

• Safe, clear isolation of three-phase circuits during maintenance or servicing
• Integrated protection to limit fault current and safeguard downstream equipment
• Maintenance-friendly operation with a pullout fuse carrier for straightforward fuse checks and changes

Practical tips for optimal use

Pair the TFP323 with compatible fuse links sized for 100A at 240V to ensure consistent protection. Plan installations with accessible fuse carriers to minimize downtime during maintenance. This switch is a strong choice wherever space is at a premium but reliable isolation and protection are non-negotiable—think motor control centers, compact switchgear, and service panels in industrial facilities.

Why choose Siemens for this application

Siemens combines decades of electrical engineering with practical field experience to deliver a pullout switch that not only meets performance specs but also integrates smoothly into existing protection schemes. The TFP323 delivers a robust, maintainable solution that helps keep industrial processes running smoothly while providing clear, dependable isolation when service is required.
