AF50 ... AF95B 3-pole contactors

22 to 45 kW with 1 N.O. + 1 N.C. auxiliary contacts
DC operated - connection with standard ferrules

Description
AF50 ... AF95B 3-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 3-phase motors and power circuits up to 690 V AC (AF95B up to 1000 V AC) and 220 V DC.
2 These contactors are of the block type design with 3 main poles.
1SBC101363F0010 – designed in accordance to the applicable parts of IEC 60077 and EN 50155 standard (3)
– shocks and vibration withstand conforming to IEC 61373 (category 1, class B) (4)
– fire and smoke safety compliance to european standard EN 45545 (AF50 ... AF75: HL2, HL3; AF95B: HL2
hazard levels) and north american standards ASTM and BSS 7239 standards (AF50 ... AF75)
AF50-30-11 – 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 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.
