BIMETALLIC-STRIP THERMAL RELAY Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: relay is provided, in addition, with bent bimetallic strip placed between case bottom and clapping bimetallic sensing element which comes in contact with the latter through its unlike-polarity layers; with temperature varying from initial value to direct-operation clapping temperature strip reduces its bending and does not interfere with bending of clapping sensing element while pusher remains motionless. EFFECT: improved reliability and parameters of bimetallic-strip thermal relay. 5 dwg
