Belimo BFN230-T/300

Spring-return actuator with BAT thermal release (72°C), designed for 90° fire and smoke dampers in ventilation and air-conditioning systems. When powered, the actuator moves the damper to its operating position and tensions the spring. If the power supply is interrupted, the spring moves the damper to its safety position.
