AF45..RT ... AF75..RT 4-pole contactors
100 to 125 A AC-1
DC operated - connection with ring tongue ferrules

AF45..RT, AF75..RT 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
1SBC590077F0304 • shocks and vibration withstand conforming to IEC 61373 (category 1, class B)
• 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
AF75-40-00RT
IE 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 or side mounting and a wide range of accessories.
