Middle Atlantic FC-4A Thermostatic MPR Module Fan Controller

Keep rack-mounted AV, IT and security systems running reliably with the Middle Atlantic by Legrand FC-4A thermostatic fan controller. Built for professional installations, this fan controller automatically adjusts fan speed to maintain optimal enclosure temperatures, protecting sensitive electronics and reducing service calls. The FC-4A controls up to four AC fans (max load 1 A at 120V), features three user-selectable temperature ranges and includes a 5 ft temperature probe for precise monitoring of internal conditions. Proportional speed control lowers noise and extends fan life by avoiding constant full-speed operation, making it ideal for surveillance, monitoring and network equipment closets. Designed to mount in MPR series raceways and to work with Middle Atlantic AC fans or similarly specified models, the FC-4A offers straightforward setup and intuitive status LEDs for quick diagnostics. UL-listed and finished in durable powder coat, it integrates seamlessly into professional rack deployments. For quieter, more efficient cooling in security, networking and AV racks, choose the FC-4A fan controller — add it to your next enclosure or retrofit project to improve uptime and performance.
