Latching Relay, Electrical Reset: RADE series
The RADE series are latching relays, either hand reset or electrically reset. 
These relays are bistable: the contacts will remain in either the "tripped" or "reset" state until one of the coils is energised (or the relay is manually reset).
Both "trip" and "reset" coils are available with various voltage ratings, either alternating or direct current.  
Three variants are available: 
RADE2030: 3 change-over contacts 
RADE3080: 8 change-over contacts 
RADE4160: 16 change-over contacts

They may be used to perform lock-out functions.
ANSI function: 86
