CIRCUIT BREAKERS - ANSI Standard

In Microelettrica, we design, manufacture, and sell a complete range of High Speed Circuit Breakers for railway fixed applications. Our 80-year worldwide experience guarantees very high reliability and low maintenance of our products. High performances are achieved through a strongly optimized design, which ensures a robust dimensioning of components combined with reduced weight and costs. The extreme making and breaking capability is the evidence of our will to be the best partner in the rail market.

The Railway fixed application IR series is certified according to IEC 61992, ANSI C37-14 and is suitable for DC substations as:

  • Rectifier circuit breaker
  • Line circuit breaker
  • Interconnector circuit breaker

 

The Railway fixed application IR series is certified according to IEC 60947 for heavy industry and energy production.
