Why Choose the ABB NFB80EK-14 Contactor Relay?
The ABB NFB80EK-14, order code 1SBH137063R1480, is an 8-pole contactor relay designed for switching auxiliary and control circuits in railway rolling stock. As part of the ABB NFB railway contactor relay range, it features eight normally open contacts and is designed to meet key requirements for electrical equipment installed in demanding railway environments.
The NFB80EK-14 features an electronic coil interface with a wide 250–500 V AC 50/60 Hz and 250–500 V DC control voltage range. Its low 1.7 W holding power helps minimise control-circuit energy consumption, while integrated surge suppression removes the need for additional external coil suppression components.
With 8 NO auxiliary contacts, a rated switching current of 4 A and a rated operational current of 3 A at 400 V AC, the NFB80EK-14 provides multiple switching paths for signalling, interlocking and control functions. Its compact 45 mm width, Push-in Spring terminals and DIN rail or screw mounting support efficient installation in railway electrical cabinets.
