Construction

The components of the Brahma AT5 18021002 relay are placed on a pressed frame made of thermosetting material with high dielectric resistance. The plastic case provides reliable protection of the device from possible damage that may occur due to collisions, careless opening, exposure to dust and air. Flexible unipolar conductors of various sizes connect the control components, excluding only the flame detection circuit. This design not only ensures the effective functioning of the control system, but also prevents possible malfunctions, ensuring a long service life of the device.
