Feeder
Feeder is the control logic customized for the load
controlled by circuit breaker directly without using
a contactor. The feeder application in M10x pro-
vide measurement and control functionality only.

* The assigned DI and PIN code may change in actual design
Depending on the type of the load, pro-
tection functions which are designed
for motors in M10x may not be suitable
for feeder load and shall be carefully se-
lected or switched off.
• Operating:
Start 1 command activates contactor output relay
CCA for 2 seconds. Start 2 command activates
contactor output relay CCB for 2 seconds.
External trip occurs a trip message and will be re-
set when the signal is inactive.
• Monitoring:
Circuit breaker close/open status Circuit breaker
trip
• Protection:
Motor protection functions are not suitable for
feeder application. All protections except earth
fault protection in M10x are automatically
disabled during parameter setting when feeder
type is selected.
• Measuring:
Current, voltage are measured by M10x. Power,
energy and other parameters related to power
factor are NOT correct and should not be referred
to.
Feeder application is customized as following,
