This Three-Circuit Trunking LED Linear Bar with an aluminium housing provides excellent thermal conductivity and offers a great resistance to high temperatures. Featuring a 90º polycarbonate opening angle that offers optimal brightness in hallways and passing areas. This Trunking LED Linear Bar can be connected in series and allows us to create linear lighting structures. Its electrical connections are made up of 7x wires that are 2,5mm². It allows us to connect up to 50 luminaires, making up a 75 metre chain without losing voltage. The luminaire can transport 3x electrical circuits and neutral (L1, L2, L3 and N). It's electrically isolated by wiring the Earth (GND). To regulate the brightness of this Trunking LED Linear Bar, connect the 1-10V Dimmer (see accessories) to the DIM1 and DIM2 wires. The connection features a mobile piece that allows us to choose an electrical circuit with which we'll feed the Trunking LED Linear Bar. In this way we can have three independent switches acr
