Instantaneous relays

CU-U200-B relay - High contact life

Summary

Description

Miniature railway relay with two change-over contacts. Equiped with magnetic arc blow-out for higher contact life. The contacts are weld-no-transfer contacts: they are mechanically forced in the same position. Relay for plug-in mounting (CU version) or for PCB mounting (CP version).
 
The construction of the relay and choice of materials makes the CU/CP-U200-B relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments.
 
With a very compact design and a wide range of sockets, the CU/CP-U200-B relay is an easy and flexible solution to use.

Application

These relay series are designed for rolling stock applications where available space is limited. The CU/CP-U200-B is used in applications where a high
contact life is required.
