Issues regarding the selection of installation rates for the commissioning of AC asynchronous motors
Thread Content
I would like to ask: regarding the adjustment of asynchronous motors, should one choose a model with **overcurrent protection** or one controlled by a **knife switch** for determining the appropriate specifications? Thank you!
Such a professional question. I didn’t make a budget. :Lol, it has passed the inspection; P. It’s better to choose ones with overcurrent protection – it seems that you can also get some payment for circuit debugging. Generally, the number of debugging circuits is determined based on the number of circuit breakers: Lol. In other words, if there are circuit breakers at both ends, it can be counted as 2 circuits: Lol
To decide whether to choose 【With overcurrent protection】 or 【Knife switch control】, one should consider the main circuit: if it consists of contactors and thermal relays, the former should be selected; for those that start up directly, the latter should be chosen.
