The motor protector 2MM consists of a metal housing that holds and protects the inner components against infiltration as well as mechanical deformation. The can contains the calibrated Klixon® disc carrying a silver contact. The fixed contact is placed on the opposite side, separated from the terminal by an insulator. The 2MM is available in two versions: with epoxy insulation and with additional sleeve. The operating principle of the 2MM is both simple and effective. A current flows through the resistive Klixon® bimetal disc. When a fault condition occurs, the increased current and ambient temperature make the bimetal disc snap open the contacts. The contacts close again automatically as the device cools down to a safe running temperature.

In single phase motors it can be mounted directly in the main circuit to serve as on- or in-winding protector. It’s compact size provides ease of installation, even in small spaces. At this time there is practically no small motor the 2MM cannot protect against overheating and overloading. Sensata Technologies 2MM provides you with a cost effective solution in terms of maximum quality and reliability.
