Abstract
The stray inductance created by the loop formed by voltage sensing conductors connected to opposite ends of the bimetal in a miniature circuit breaker for determining load current is reduced by joining a voltage sense bar to the free end of the bimetal. The voltage sense bar extends beside the bimetal toward the fixed end of the bimetal where an insulated wire connected to the free end of the sense bar forms a twisted pair with an insulated wire secured to the fixed end of the bimetal.
