The 4-pole AF140B contactors meet the latest standards for rolling stock and allow installation in passenger or driver's cabs of trains that frequently travel in tunnels or underpasses. They switch power circuits with motors, slightly inductive or non-inductive loads. They meet all important standards for rolling stock: IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2 and applicable parts of the EN 50155 standards, shock and vibration resistance according to IEC 61373 Cat. 1, Class B. They also achieve the highest levels of fire and smoke behavior while complying with the European standard EN 45545-2 (HL2 hazard levels) when mounted in groups. All integrated or subsequently fitted auxiliary break contacts are designed as mirror contacts according to IEC60947-5-1 Appendix L. Only 4 coils cover control voltages from 20...500 VDC to 24...500 VAC. They also have built-in overvoltage protection and do not require any additional suppressors.
