Belimo FSLF120-S US : Fail-Safe Fire & Smoke Actuator, 30 in-lb, 120VAC, On/Off Control Signal, (2) SPDT 3A @250V Aux Switch, 5-Year Warranty
The Belimo FSLF120-S US actuator operates effectively in HVAC systems with an AC voltage of 120V and 50/60 Hz frequency. Its power consumption is 18 VA during operation and 4 W at rest. This reliable actuator features dual auxiliary switches with a switching capacity of 3 A resistive (0.5 A inductive) at AC 250 V, positioned at 10° and 85°. The torque motor delivers 30 in-lb [3.5 Nm] at 350°F [177°C] for 30 minutes, while its 0 to 95° rotation angle and reversible motion ensure precise control. It meets UL2043 compliance, cULus, NYC Department of Buildings MEA 197-07-M, and California State Fire Marshal Listing 3210-1593:102 standards. With noise levels at 45 dB(A) during operation and 62 dB(A) during fail-safe mode, this maintenance-free actuator thrives in temperatures from -40°F to 176°F. It weighs 4.4 lbs.
