9 - Additional protections and functions
Additional protections
Some protections have additional functions which extend their characteristics and performance:
Name Description Protections
Thermal
Memory
Reduced trip time in the case of TRIPs within brief
intervals (protection against cable overheating)
L, S
Zone
selectivity
Additional parameters for managing TRIP commands
between circuit-breakers equipped with the same
function
S, S2, G, D, Gext
Blocks
Blocking of protection on the basis of programmable
events
S, I, G, MCR, S2, D, S(V), S2(V), UV,
OV, VU, UV2, OV2, UP, OP, RP, RQ,
OQ, RV, UF, OF, UF2, OF2, ROCOF,
Gext
Startup
Different threshold of the protection for a limited
time, with activation on the basis of a programmable
monitoring threshold
S, I, G, S2, D, UP, Gext
Additional protections
Installation of certain accessories allows the additional protections to be activated:
Name Type of protection Threshold Time Function Additional functions
Gext
Earth fault with current
reading by S.G.R.
external sensor
Trip enable, Zone Selectivity,
Startup enable, Block,
Prealarm Threshold
Rc
Residual current with
corrent reading by
external toroid Rc
Synchrocheck
Synchronism between
two independent voltage
sources or energizing of
a busbar not active
Further details about the protections are given in document 1SDH001330R1002.
Programmable Functions and
Commands
Ekip Touch has eight programmable commands, which activate on the basis of signals or events. Each
command allows the activation function and event monitoring time to be programmed.
