9 - Additional protections and functions

Additional protections Some protections have additional functions which extend their characteristics and performance:
Name Description Protections
Thermal Reduced trip time in the case of TRIPs within brief L, S
Memory intervals (protection against cable overheating)
Additional parameters for managing TRIP commands
Zone between circuit-breakers equipped with the same S, S2, G, D, Gext
selectivity
function
S, I, G, MCR, S2, D, S(V), S2(V), UV,
Blocking of protection on the basis of programmable OV, VU, UV2, OV2, UP, OP, RP, RQ,
Blocks
events OQ, RV, UF, OF, UF2, OF2, ROCOF,
Gext
Different threshold of the protection for a limited
Startup time, with activation on the basis of a programmable S, I, G, S2, D, UP, Gext
monitoring threshold

Additional protections Installation of certain accessories allows the additional protections to be activated:
Name Type of protection Threshold Time Function Additional functions
Earth fault with current Trip enable, Zone Selectivity,
Gext reading by S.G.R. Startup enable, Block,
external sensor Prealarm Threshold
Residual current with
Rc corrent reading by
external toroid Rc
Synchronism between
two independent voltage
Synchrocheck
sources or energizing of
a busbar not active

Further details about the protections are given in document 1SDH001330R1002.

Programmable Functions and Ekip Touch has eight programmable commands, which activate on the basis of signals or events. Each
Commands command allows the activation function and event monitoring time to be programmed.
Name Description Menu path
External Trip Sends a TRIP command
RESET Trip TRIP signal reset Advanced - Functions
Activate SET B Changes the protections set, from Set A to Set B
Energy RESET Resets the energy meters Measurements - Energy
Command YO Sends a command to opening coil YO Settings - Functions
Command YC Sends a command to closing coil YC
LOCAL Switch On Changes the configuration, from Remote to Local Settings - Modules
Signaling RESET Reset the contacts of the signalling modules - Functions
