ABB Ltd. is exploring a potential sale of the robotics unit, which could be worth more than $3.5 billion, as an alternative to the main spinoff plan, according to people familiar with the matter.

The Swiss industrial giant is close to appointing advisers for a sale as well as the listing, which it announced last month, the people said, asking not to be identified because the talks are private.
