Abstract

Relay has a spring-loaded contact support movable longitudinally. Its movable contacts interact with fixed contacts. It has a release element spring-loaded in the "off" direction, locked in the "in" position by a locking element controlled by a thermocouple. It can be connected to a movable contact support. Means are provided for resetting the release element from the "out" position to the tripping position. The release element is in the form of a supported on a fixed pin lever (20). The locking element is at its one end, and the spring (24) pressing it in the "off" direction is at its other end.
