● Customized Load: Set when a device that needs to be congured with a
disconnection mode and disconnection parameter is connected. (The default
disconnection mode is Voltage Mode, and the default disconnection voltage
is 44 V.)
● BLVD Load: Set when primary loads are connected.
● Power Cascading Port:
– Set when a DC power distribution unit (such as iDMU48-300B-17A) that
supports the measurement function is added.
– Set when Huawei solar PV distribution units (such as the PVDU-100A1,
PVDU-150A1, PVDU-150A3, and PVDU-200A1) are connected in the solar
access scenario.
● DC DG: Set when a DC DG is connected. The circuit breaker can be used to
collect statistics on the DG energy yield.
● Solar Energy: Set when a third-party solar power supply unit (48 V power
supply) is connected. The circuit breaker can be used to collect statistics on
solar energy yield.
● Lithium Battery: Set based on the connected lithium battery branch.
● Lead-acid Battery: Set based on the connected lead-acid battery branch.
● Other: Set when other 48 V power supply devices are connected.
Procedure
Step 1 Set the usage of the branch based on the device connected to the circuit breaker.

12.2.4.2 Setting the Capacity of a Circuit Breaker
You can set the circuit breaker capacity when the circuit breaker usage is set to
load branch (BLVD Load/Customized Load), general power distribution branch
(Power Cascading Port/DC DG/Solar Energy/Other), or battery power distribution
branch (Lithium Battery/Lead-acid Battery).
