401 relay - Safety critical, 40 contacts

Summary

Description

The 401 relay has 40 double break contacts in all N/O and N/C combinations.
 
The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement). The resistance to impact and vibration is conform to standards in force for Railway Transported Equipment.
 
Weld no transfer safety contacts are standard. If one N/O contact welds, no N/C contact can close and visa versa. All relays are factory tested to insure they meet this important safety requirement.
 
The 401 relay can be plugged in the COR OU type socket.

Application

The 401 latching relay is especially build for double driver desk equipped locomotives and used to switch all controls of a drivers desk in a locomotive at once to the other driver desk on the other side of the locomotive.
