Belimo FSTF120 US : Fail-Safe Fire & Smoke Actuator, 18 in-lb, 120VAC, On/Off Control Signal, 5-Year Warranty
The Belimo FSTF120 US actuator operates on AC 120V at 50/60 Hz frequency, within a range of AC 96 to 132V. It consumes 2 W during operation and 1.5 W at rest, with electronic design and a 0 to 95° rotation. Providing 18 in-lb [2 Nm] torque at 250°F [121°C] for 30 minutes, it's reversible with a 95° angle. Running for 75 seconds/90° at 250°F [121°C] and less than 25 seconds at 32°F to 122°F [0°C to 50°C], it maintains noise levels at 45 dB(A) during operation and 62 dB(A) in fail-safe mode. The actuator meets IP42 and NEMA 2 standards, is cULus listed to UL60730-1A/-2-14, and carries California State Fire Marshal Listing 3210-1593:104. Suitable for NEC and IMC air plenums, it functions within 32°F to 122°F [0°C to 50°C], with storage tolerance of -40°F to 176°F [-40°C to 80°C]. This 1.6 lb [0.60 kg] maintenance-free actuator is built with UL94-5VA materials for safety.
