Belimo FSTF24-S US : Fail-Safe Fire & Smoke Actuator, 18 in-lb, 24VAC/DC, On/Off Control Signal, (2) SPDT 3A @250V Aux Switch, 5-Year Warranty

The Belimo FSTF24-S US actuator, optimized for AC/DC 24V voltage, operates seamlessly at 50/60 Hz frequency with a range of AC 19.2 to 28.8V / DC 21.6 to 28.8V. Consuming 2 W during operation and 1.5 W at rest, it offers efficient electronic performance. It features two SPST auxiliary switches with 3 A resistive (0.5 A inductive) capacity each at AC 250V, set at 10° and 80°. With a 0 to 95° rotation, this double-insulated actuator provides 18 in-lb [2 Nm] torque at 250°F [121°C] for 30 minutes. Its noise levels are 45 dB(A) during operation and 62 dB(A) in fail-safe mode. The actuator holds IP42 and NEMA 2 standards, cULus listing to UL60730-1A/-2-14, and California State Fire Marshal Listing 3210-1593:104. It is compliant with UL 2043 and is suitable for NEC and IMC air plenums. Operating between 32°F to 122°F [0°C to 50°C], it can handle storage temperatures of -40°F to 176°F [-40°C to 80°C]. With a weight of 1.9 lb [0.70 kg], this maintenance-free actuator ensures robust functionality.
