A more thorough explanation:

A shelter hearing is a type of legal proceeding where a judge decides whether a child who has been removed from their home due to suspected abuse or neglect should remain in protective care. The hearing is usually held within 24 to 72 hours after the child's removal.

For example, if a child is removed from their home by child protective services due to suspected abuse, a shelter hearing will be held to determine whether the child should remain in protective care or be returned to their home.

Another example is if a child is removed from their home due to neglect, a shelter hearing will be held to determine whether the child should remain in protective care or be placed with a relative or foster family.
