Brahma 18048620 OR3/B control box

Brahma OR3/B 18048620 controller provides a safe start, continuous monitoring of flame burning and instantaneous termination of fuel supply in emergency situations. The Brahma OR3/B 18048620 relay is a key component of heating systems for both domestic and industrial applications.

Application

– Monoblock oil burners

– High pressure washers

– Hot air generators

– Steam boilers

– Furnaces

Due to the technical and design features of the models and their variety, they can also be used for automation of kitchen stoves and installations with oil burners in domestic and industrial applications. These Brahma OR3/B 18048620 controllers completely replace the electromechanical 03 series.
