The 3-pole AFB contactors meet the latest standards for rolling railway vehicles and enable installation in passenger or driver's cabs of trains that frequently travel in tunnels or underpasses. They switch power circuits with 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. The contactors require a very low holding power of just 1.7W. All auxiliary break contacts that can be retrofitted are designed as mirror contacts according to IEC60947-5-1 Appendix L. Furthermore, they have built-in surge protection and do not require additional suppressors.
