Contact carrier, contact-carrier arrangement and low-voltage protective switching device

A contact carrier for fastening a contact element of a low-voltage protective switching device by means of a soldering operation, so that a solder layer is formed between the contact carrier and the contact element, the contact carrier comprising:

• a contacting area for the solder layer, said contacting area having a rough surface structure and is delimited by a first channel-shaped depression, said contacting area being of substantially rectangular shape and having a second channel-shaped depression formed therein and running in a shape of a sickle from a first corner to an adjacent second corner of said contacting area being a rectangular contacting area.

A contact-carrier configuration for a switching contact of a low-voltage protective switching device, the contact-carrier configuration comprising:

• a contact carrier having a contacting area for a solder layer, said contacting area having a rough surface structure and is delimited by a first channel-shaped depression formed in said contact carrier, said contacting area being of substantially rectangular shape and having a second channel-shaped depression formed therein and running in a shape of a sickle from a first corner to an adjacent second corner of said contacting area;
• and
• a contact element fastened to said contact carrier by means of soldering, so that said solder layer is formed between said contact carrier and said contact element.
