The utility model relates to a low voltage disconnecting link which comprises three identical single-phase structures, wherein each single-phase structure comprises a lower static contact. The lower static contact and an upper static contact are respectively connected with two ends of two dynamic contact blades. The head of one end of each dynamic contact blade is fixed by a bolt through a butterfly-shaped pressure spring. The middle parts of the two dynamic contact blades are fixed with bolts through bolts used by clamping plate-shaped springs. The place at which the dynamic contact blade is contacted with the lower static contact is provided with at least two round rotating contacts. The place at which the dynamic contact blade is contacted with the upper static contact is provided with at least two strip-shaped contacts. The number of contacts on the dynamic contact blades is increased, thereby increasing the contact areas between dynamic contacts and the static contacts, reducing the resistance between the dynamic contacts and the static contacts and further reducing the heat generation between the dynamic contacts and the static contacts. Under the same conditions, if the dimension is not changed, then the rated current is increased. The low voltage disconnecting link does not increase the product cost or the structure complexity and has the advantage of good safety performance.
