Brahma Relay AT5/TR 220/50

AT5/TR CONTROL BOX DESCRIPTION CONTROL BOX FOR ATMOSPHERIC The AT5fTR control box is suitable for atmospheric gas GAS BURNERS WITH POWER UP TO bumers for civil and industrial applications for power up to 350KW. 350KW WITH INBUILT IGNITION According to TÜV Bayern. Monaco, the contrai is in TRANSFORMER cornpliance with the German regulation OIN 4788, part 3, for power up to 350KW. lt also obtained the DIN-DVGW 91.02fBN approval, now expired and not renewable. The "Laboratorio diMacchine e Termotecnica del Centra Studi ed Esperienze" in Roma - Capannelle tested the A T5fTR control for power up to 350KW, which obtained the certification no. 3704/10-77/8 and the approval of the Ministry of the lnterior for tire prevention (circulars no. 68 and no. 42).
