Latest Patents

Ken-ichi Abe holds a patent for a multi-polar circuit breaker. This invention articulates the neutral-pole switching element in a multi-pole circuit breaker. By providing spring biasing to urge the two elements into a pre-determined position approximating alignment, he advances the neutral pole switching element with respect to the other switching elements. The design includes fixed contact elements that frictionally engage opposite sides of the neutral-pole switching contact in the closed position. This mechanism ensures that the closing of the neutral circuit precedes the closing of the live circuits, while the opening of the neutral circuit lags the opening of the live circuits. This innovative design prevents arcing and transient damage to loads on the circuit.
