USED Heinemann Circuit Breaker - Model and Rating UNKNOWN ?This was removed from equipment. The sticker is missing. It APPEARS to be a 15 AMP JA3-A3-A Circuit breaker but please verify this before purchasing.? This is surplus material from our home. We are downsizing. I am hoping it is exactly what you are needing! Excellent for those who like to surround themselves with quality stuff! Flat rate shipping & handling in continental, lower 48 states in USA: $3.99. All my items are from a smoke free, pet free home.
