GAF75..RT 1-pole contactors comply with the latest railway rolling stock standards and allow installations in passengers or driver cabins for trains frequently operating tunnels or undergrounds. They are mainly used for controlling shunt or series motors and resistive or slightly inductive loads up to 1000 V DC. These contactors are of the block type design with main poles connected in series. – main poles arc chutes fitted with permanent magnets specially designed for DC breaking. The connection polarities must be respected. – shocks and vibration withstand conforming to IEC 61373 (category 1, class B) – fire and smoke safety compliance to european standard EN 45545 (HL2 and 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 battery supplies. For AC control supply, please consult your ABB sales representative. – built-in surge suppression – side by side mounting without restriction from -40 °C up to 70 °C – add-on auxiliary contacts blocks for front or side mounting.
