AF45 … AF75 4-pole contactors

70 to 125 A AC-1
DC operated - connection with standard ferrules

Description
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
2 690 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)
– 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 IEC 60077) used for
AF75-40-00 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.
