Thermal actuators with pushing action, for fire dampers, operated by eutectic fusible link

These mechanical thermal actuators are intended to close the fire dampers used on the ventilation ducts. Their large operating force unlocks the spring actuating the damper. Requiring no power supply, these devices are particularly simple and reliable. They are mandatory for all fire dampers to meet the NF-S 61.937 standard.
