The ZBAE72 is a replaceable thermal fuse (Tf2) designed for installations with the BAE72-S unit. The fuse responds to the temperature inside the air duct and, upon reaching the trigger value, permanently disconnects the actuator's power supply, ensuring the damper returns to a safe position.

Thanks to its easy replacement and mechanical probe, the ZBAE72 is suitable for regular servicing of fire and smoke dampers with a return spring. The component is intended for systems with 24 V spring drives in combination with the BAE72-S tripping unit.

Main Features

• Trigger temperature of 72°C for inside the duct (Tf2)
• Permanent power disconnection after activation – safe damper return
• Replaceable part for BAE72-S, easy servicing
• Mechanical probe for precise temperature sensing inside the duct
