RELECO Railway relays series MRC, QRC

RELECO railway relays type R3 RELECO railway relays type R7
R3-N3x… R7-x…

All these relays are produced and tested according to the EN  60077-1-2/99 and EN 61373/99 and IEC  67-i-18a.

Relays according to Railway standard (increased shock and vibration resistance).
Relays as per railway standard EN50155/EN60077/EN61373 are more suitable for applications with shock and vibration and have a higher degree of surge protection.
Many of these railway relays also comply to additional fire protection standards, have lower inflammability and develop less toxic smoke and gases in case of fire.
Relays specially developed to comply with railway standards are designed for higher vibration, shock and surge values and allow higher tolerance in the voltage supply.
Some of these relays additionally comply to special fire protection standards in regard to inflammability and the development of toxic smoke and gases in fire accidents.
Although specially designed for railway applications these relays are also suitable for other industrial applications where increased product safety is required.
Suitable relays for this application:
