What does this mean? If more than the specified current is being drawn, will it disconnect the circuit? Attachment LOGO_Contact_24.png (351 Downloads)

The question does not refer to a digital input of the LOGO! but to the contactor "LOGO! Contact". https://mall.industry.siemens.com/mall/en/b1/Catalog/Product/6ED1057-4CA00-0AA0

I'm sorry, sumit_b means protection, which must be inserted at the input of this contact. short-circuit are the maximum current that the contact can withstand and the passage of more current will damage it.

The LOGO! Contact 24 are normally contactors with a housing in Logo design. Short-circuit protection means, you have to protect the contacts of the contactor with fuses type 1 25A or type 2 10A. There is no integrated protection in the Contact 24. Regards, Scorp
