Material Notes:
ELKONITE® 4050 is a high silver material that uses a special tungsten powder. It is made by the press-sinter-infiltrate method. It was developed especially for use as a combination current carrying and arcing contact for molded case circuit breakers. Its strong structure improves its arc erosion resistance while maintaining good temperature rise and current interruption characteristics. ELKONITE® 4050 has approximately the same silver content as ELKONITE® 50S, but has higher mechanical properties due to its higher sintered strength. It is used in the higher rated household breakers.Information provided by CMW Inc.
