11.5.4 “Electronic Circuit Breaker” Mode
In this mode, a specified trip current and trip delay can be set via the WAGO Interface
Configuration software or a connected
8 communication module [ } 70] . If the output
current exceeds the trip current setting, a specified amount of time elapses. If the output
current is still higher than the trip current setting after the trip delay corresponding to the
setting, the output is switched off. To switch the output back on, manual intervention is
necessary. The following options are available for this:
• Communication interface
• Buttons
• Digital input

11.5.5 “Latching Shutdown on Thermal Overload” Mode
In this mode, the output voltage is switched off in the event of excessive internal device
temperature. A corresponding “High Device Temperature” warning can, for example, be
transmitted via the WAGO Interface Configuration software or passed to a higher-level
controller via a connected
8 communication module [ } 70] . To switch the output back
on, manual intervention is necessary. The following options are available for this:
• Communication interface
• Buttons
• Digital input
11.5.6 “Power Boost” Mode
This mode can be used in combination with the following modes:
•

•
8
“Electronic Circuit Breaker” Mode [
}
65]
In this mode, output current equal to 150 % of the nominal output current is permitted for
5 seconds. The output is then switched off. To switch the output back on, manual inter-
vention is necessary. The following options are available for this:
• Communication interface
