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, MDGF
Blocks
Blocking of protection on the basis of
programmable events

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.
