No neutral required design reduces wiring complexity, cutting installation time and panel derating. This translates to lower labor costs and faster commissioning, especially in retrofit projects where space and conductors are limited. The SFS5-LA is a 120 V single‑phase fan controller optimized for 60 Hz systems, making it a natural fit for commercial ventilation and industrial cooling applications. Flush mounting and back‑and‑side wiring offer flexible installation options without altering enclosure dimensions. This compatibility minimizes field modification, preserves enclosure integrity, and simplifies panel layouts in busy plant environments. It is well suited for panel-mounted fans in HVAC cabinets, process equipment, and automation stations. Polycarbonate housing in light almond provides durable, impact‑resistant protection in factory environments. The material and finish support easy cleaning and long‑term reliability in dusty or humid plants. The color and texture blend with existing control panels, reducing miswiring and misidentification. With a torque rating of 14 lbf‑in and a 60 Hz, 120 V single‑phase profile, the SFS5-LA delivers consistent fan control across a range of lightweight to medium‑duty fans. The no‑neutral design also reduces conductor runs, improving installation efficiency and compliance during future upgrades. This translates to lower total cost of ownership over the equipment lifecycle. Certified as cULus Listed, the device meets essential electrical safety standards and supports audits in manufacturing, data centers, and building systems. Built for back and side wiring, it integrates into existing control networks with minimal disruption and provides a reliable, scalable solution for evolving ventilation strategies. The result is safer operations, easier maintenance, and a smoother path to regulatory readiness.

FAQs
The SFS5-LA uses back and side wiring with a flush-mount installation, and it operates at 120 V with 60 Hz single‑phase power. Begin by ensuring the panel is de-energized, connect the line and load conductors to the back and side terminals as per Eaton's wiring diagram, secure the device in the mounting opening, and restore power to verify proper operation. No neutral is required, which simplifies wiring in retrofit panels.
Key specs include a 120 V voltage rating, 60 Hz frequency rating, single‑phase operation, single‑pole configuration, and a torque rating of 14 lbf‑in. It is designed for back and side wiring and flush mounting, supporting fan loads in industrial ventilation and HVAC applications.
Yes. With no-neutral operation, flush mounting, and a 120 V single‑phase, 60 Hz rating, the SFS5-LA is well suited for panel-mounted ventilation fans across commercial buildings, process equipment, and automated systems where space is constrained and wiring efficiency matters.
The SFS5-LA is cULus Listed, indicating compliance with essential electrical safety standards. This certification supports regulatory compliance during audits, reduces risk in manufacturing and facility environments, and provides confidence when integrating the controller into standardized control networks.
Benefits include reduced wiring and installation time due to no-neutral design, simplified retrofits, and lower labor costs. The compact, durable polycarbonate housing and flush‑mount form factor also support long-term reliability in demanding environments while enabling scalable upgrades as ventilation needs evolve.
