BELIMO BFL24-T Fire Damper Actuator (BFL Series)

• Torque: 4 Nm motor torque / 3 Nm spring-return torque.
• Nominal Voltage: AC/DC 24 V (50/60 Hz).
• Control Type: Open/close operation.
• Running Time: ~60 seconds to open.
• Mechanical Interface: Form-fit 12×12 mm continuous hollow shaft.
• Integrated Switches: 2 x SPDT (Single-Pole Double-Throw) auxiliary switches for position signaling.
• Degree of Protection: IP54 (dust and splash water protection).
• Thermoelectric Tripping Device (BAT): It comes equipped with a thermal sensor set to trip at 72°C. If the ambient or duct temperature hits this threshold, it permanently interrupts the power supply, causing the internal spring to slam the damper shut safely.
• Fail-Safe Function: In normal operation, the electric motor holds the damper open. During a power failure or fire emergency, the mechanical spring energy takes over to completely close the damper and prevent the spread of smoke and fire.
• Service Life: Rated for a minimum of 60,000 safe positions.
