FIELD: instrument recording electric power consumption. SUBSTANCE: two windings are wound on rod of closed magnetic circuit. Control electrodes of two simisters and cut-off winding built-in automatic circuit breaker are connected to leads of windings through two rectifiers. Circuit-breaker contacts open phase and neutral wires at single-phase counter output. Electric counter features enhanced cut-off capability in cases of misuse and failure in operation. EFFECT: higher reliability, prolonged service life. 2 dwg
