Review on 💥 Optimized Stinger SG-P90300 300 Amp Circuit Breaker by Kaveen Reyes

Revainrating 1 out of 5

There she blows - again!

This is a terrible circuit breaker and should not be placed on the market due to its misleading amperage rating. As others have said, it doesn't have nearly as much power as the rating suggests. This circuit breaker also has bad contacts as they arc internally and have wreaked havoc on my arcing fault detectors. I went insane trying to find the culprit in my solar system and was surprised to find that all my problems went away when I replaced this breaker with a fuse of the same rating. I really regret buying this product and wish I'd lived up to other reviewers warnings. I even bought a 200 amp version with the same disastrous results! My spare 200 amp fuse won't blow, so why does this product blow every time I charge it at much less current than its rating allows? Something is definitely not right here.

Pros
  • Very good value for money
Cons
  • Unbelievable price
