Hello
Today, i needed to power my water tank pump (400W) because power outage.
So, i plugged the pump on the EB3A and … EB3A breaker switched off
As i know, the EB3A is given as 600W in 220V AC output
The KIKAWA pump spécifications are :
OUTPUT : 0.4kW
VOLTAGE : 220V / 230V
AMPERE : 2.5A
The AC Output BLUETTI EB3A spécifications are :
POWER : 600W
SURGE : 1200W
VOLTAGE : 220-240V
AMPERE : 2.6A
Each time i try to power the pump from the EB3A, the EB3A circuit breaker switch off
How can you explain this ?
Thank you for your inquiry. Regarding the issue with the water pump, here is an explanation:
The water pump is an inductive load, and its core characteristic is that the starting instantaneous current is significantly higher than the rated current. This is the fundamental reason for the EB3A circuit breaker tripping. The rated parameters of the water pump are: 400W, 220V, and 2.5A, which represents the current during stable operation.
However, during the motor’s startup, the inrush current can be 3 to 7 times the rated current. Therefore, the starting current of the water pump can reach 7.5 to 17.5A.
The EB3A’s AC output limit is a rated current of 2.6A, which is the maximum current for continuous operation. Although the EB3A is marked with a surge power of 1200W, this power only lasts for a very short duration (usually only milliseconds), while the startup process of the water pump typically takes hundreds of milliseconds to several seconds. The surge power cannot sustain this duration, ultimately triggering the overload protection to trip.
I hope this information helps you understand the situation better. If you have any further questions, please feel free to contact me.
