OUTPUT:
Output Relays:
BREAKER TRIPPING (“TRIP”): Six sets of N.O. contacts, rated for
5 amperes continuous, 40 amperes for 0.2 seconds.
DTT OUTPUT (“DTT”): Two sets of N.O. contacts, rated for 5 am-
peres continuous, 40 amperes for 0.2 seconds.
Trip Output Seal In:
CCS or DTT Trip output contact is held closed with >200mA Trip
Current detected.
CCS Trip output contact has programmable trip release algorithms.
• Trip plus DC current sense
• Trip plus 100 ms
• Trip plus 0 ms
DTT trip output contact is released when <100mA trip current and
not trip signal present for at least 100ms.

Communications Alarm: One set of Form C (SPDT) contacts, rated
0.1 ampere @ 125 Vdc.
System Alarm: One set of Form C (SPDT) contacts, rated 0.1 am-
pere @ 125 Vdc.
