Federal Pacific Electric Co was purchased by the Challenger Electrical Equipment Co in the 1980's and all residential, commercial and industrial products were discontinued. Challenger continued manufacturing replacement breakers for a brief time and when later bought out by Cutler-Hammer, the Stablok replacement was produced by a new entity called American Circuit Breaker. Stablok products are no longer manufactured. While a limited line of ETL Listed replacement breakers manufactured by Connecticut are presently available, no Ground fault, Shunt Trip or Switched neutral breakers are available. Your solutions are replace the existing panel or sub-feed to a separately enclosed breaker of another brand. Call customer service for suggestions.
