1. Cooling fan (2-3 years)
As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally the shortest service life of the accessories, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.
2. Relays & Contactors (2-3 years)
The second type of wear is relays and communication contactors. Since the relay and the communication contactor are frequently engaged, it is easy to form poor contact of the contact, so it should be replaced according to the use of the contact, and try to choose a big brand and a good quality contactor and relay, so that the service life will be longer.
3. Filter capacitors (4-5 years)
The DC circuit of the inverter uses a large-capacity electrolytic capacitor, and its function will gradually deteriorate due to the influence of factors such as pulse current. In general, the service life is about 5 years, the maximum inspection period is 1 year, and the inspection cycle is 1 time every six months when it is close to life.
4. Fuse
Under normal use conditions, the life of the fuse is about 10 years, and it generally does not need to be replaced unless it is incinerated.

Delixi molded case circuit breaker Icu=ICS understands
Delixi 3P air switch, additional current 630A, additional voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? Assuming it works, the ICU is now at its limit, which is paradoxical. Assuming it can't be used, Ics is 70KA, clarifying ...
