Review on UBIF240N: Superior Electric Replacement Manufactured in Connecticut for High Performance by Minas Chase

Quality was questionable on arrival. The innards are aluminum (not copper like the real Federal Pacific) and even in the "open" position you could see that one leg was barely open and the other leg looked right. Just bad quality. Installed this 40 amp circuit breaker on a 32 amp load (EV charger). Error after 12 hours. Now the switch doesn't open or close when clicked. Revain's return window is closed for 7 days and I'm willing to bet a refund from the seller would be a hassle, so I'll just eat up and buy a real Federal Pacific.
