Tips: Why do you need to buy an ATO AC magnetic contactor?

The AC magnetic contactor is generally used to start and control equipment. It uses different control wiring methods to control the forward and reverse rotation, start and stop of the electrical motor, and can realize remote control by controlling the length of the cable. Changing the connection can also realize multiple controls. In the state of power failure, the motor can be stopped to prevent it from running due to the power on again, which will protect the operators from unforeseen injuries. Of course, the motor can be started manually after the power goes on again. The AC contactor can be used together with an overheating relay or a motor protector to achieve the purpose of protecting the motor.

Some questions about AC magnetic contactor

I’m not sure that I have the right part. Here is a picture of the contacts that I received. My understanding is that these would have normally closed contacts, rather than normally open contacts.
I need normally closed contacts for the 400Amp connection itself, not for ancillaries. I need to make sure that the main contacts are normally closed so that they only open when I energize the coil.

ATO Responded

The contact has Mo main circuit normally closed contacts, only normally open contacts.
Only auxiliary contacts can be normally closed.
But do not worry, we will resend you the normally closed auxiliary contact parts.
