Note: The power consumption of the circuit breaker refers to the power consumption of the main circuit measured by the
rated current of the circuit breaker at normal temperature, excluding the power of other accessories with the power
consumption of the circuit breaker. The data in this table is for users' selection reference only, and cannot be seen as the
circuit breaker’s actual power consumption when in use.
