Relays used for railway rolling stock are subject
to increasingly higher technical demands – such
as the need for wider operating ranges; higher
resistance to shock and vibration; operation over
a wider range of temperature and humidity; and
above all, the fire resistance properties of the
relay’s constituent parts.
The resistance against random vibrations and shock of the relays and their sockets and accessories is in compliance with the prescription of EN 61373 standard for Category 1, Class B products.
Their resistance to temperature and humidity is in compliance with the prescription of EN 50155 standard, TX class (for relay and sockets) or T1 class (for timers and control relays).
The relays and their sockets and accessories are manufactured using specific insulating materials, which satisfy the requirement R26 of fire protection prescribed by the standard EN 45545-2 +A1:2016 for product category EL10.
The requirement R26, for Hazardous levels HL1 to HL3, is the conformity to V0 class following vertical small flame test according to EN 60695-11-10.
