AF45 … AF75 4-pole contactors
70 to 125 A AC-1
DC operated - connection with standard ferrules

AF45 ... AF75 4-pole contactors comply with the latest railway rolling stock standards and allow
installation in passengers or driver cabins for trains frequently operating tunnels or undergrounds.
They are mainly used for controlling non-iductive or slightly inductive loads and generally for controlling
power circuits up to 690 V AC and up to 220 V DC. These contactors are of the block type design with
4 main poles.
• designed in accordance to the applicable parts of IEC 60077 and EN 50155 standard
1SBC582703F0301 • shocks and vibration withstand conforming to IEC 61373 (category 1, class B) 03
• fire and smoke safety compliance to european standard EN 45545 (HL2, HL3 hazard levels)
• electronic coil interface accepting a wide DC control voltage range (0.85 Uc min. ... 1.1 Uc max.
according to IEC 60947-4-1) including several Uc control voltages (0.7 ... 1.25 Uc according to
AF75-40-00 IEC 60077) used for battery supply
• built-in surge suppression
• side by side mounting without restriction from -40 °C up to +70 °C
• add-on auxiliary contact blocks for front and side mounting and a wide range of accessories.
