The invention relates to an electromagnetic contactor with a counter, which comprises an electromagnetic contactor, a counter, a counter driving piece and a movable contact support, wherein the electromagnetic contactor comprises a shell; the movable contact support is arranged on the electromagnetic contactor; the counter driving piece is arranged on the counter; the end part of the counter driving piece is connected with the movable contact support; and the counter driving piece is driven to move through the movable contact support, and thus, the counter driving piece triggers the counter for counting. The electromagnetic contactor with the counter has the advantages that the structure is simple; the design is reasonable; the assembly is convenient; an auxiliary contact of the electromagnetic contactor is not occupied; the electric contact acting times can be counted reasonably; the electromagnetic contactor can be maintained and replaced at a proper time; and the economy and the security in the use of the electromagnetic contactor are improved.
Description
technical field [0001] The invention relates to an electromagnetic contactor, in particular to an electromagnetic contactor with a counter. Background technique [0002] Electromagnetic contactors are widely used in industrial automation control equipment. Due to the difference in the use environment and frequency of use, the actual number of operations of each electromagnetic contactor varies greatly. The electromagnetic contactor data provided by the manufacturer includes mechanical life and electrical life. Since the damage to the contact is much greater than that of the uncharged action, the electrical life is much lower than the mechanical life. Generally, electromagnetic contactors are used with electricity, so in practical applications, the number of electrical life is generally concerned. [0003] If it is determined whether the electromagnetic contactor needs to be repaired or replaced according to the uniform use time, since the actual number of electrified acti...
