Applications
Simple device for fire detection in buildings. This device is operating electrical contacts for remote alarm and simultaneous control of electrical servo-controls such as electric cylinders, electric motors or solenoids, for opening or closing air conditioning dampers, doors, sunroofs, and openings in building facades.
Main Features
Thermal sensitive part: Thermal bulb.
Operation: The break of the bulb operates an electric switch.
Mounting: Body with 2 holes for mounting on the wall or ceiling.
Electrical contact: Opening when the bulb breaks.
Rating: 16A (4A) 250V alt.; 10A (1A) 400V alt.; 4A (100mA) 24 and 48VDC. Compatible with 24V and 48V, 500 N electro-magnet.
Selection of gold-plated silver contact avoids oxidation, and allows use on low level electronic circuits. NB: use on circuits with a voltage greater than 12V and at more than 1A may vaporize the protective gold layer.
Body: 17 x 58 x 22 mm ceramic, with UV-resistant black PA66 cover,
- Flammability: UL94V0 and GWFI 960°C.
- Deformation temperature under load: 225°C. (ISO 75-2, 1.8 MPa).
- Room temperature class T200°C.
Electrical connection: Screw terminals for wires up to 2.5mm².
Maintenance: The replacement of the 5x20mm thermal bulb is possible after unscrewing the PA66 cover
Options: Customization and customer labelling, plastic cover in red or cream color
