Belimo BAT72-ST - thermo-electric release

Belimo BAT72-ST – thermo-electric release

The device is designed for fire dampers in ventilation and air-conditioning systems. The thermal fuses respond when the temperature exceeds 72°C inside or outside the duct. Activation of either fuse permanently and irreversibly interrupts the supply voltage. The test button allows the supply interruption function to be checked.

Key features and technical data

• Rated voltage: AC/DC 24 V; rated voltage frequency: 50/60 Hz.
• Activation temperature: inside the duct 72°C (black), outside the duct 72°C.
• Probe length: 65 mm.
• Power connection: 1 m cable with plug, 2x 0.75 mm²; Betaflam cable resistant to high temperatures up to 145°C.
• 2-pin plug compatible with BSIA24-48/-R controllers and BKN.. devices.
• IEC/EN protection rating: IP54; ambient temperature: -30...55°C [-22...131°F].
• Device tested in accordance with ISO 10294-4.

The temperature fuse outside the duct is non-replaceable; if it activates, the actuator must be replaced. The temperature fuse inside the duct can be replaced.
