Review on ⚡️ Siemens Q2020NC 120V Non-Current Limiting Circuit Breaker by Tim Wheeler

Revainrating 5 out of 5

Q2020NC is required for older panels. Q2020 does not work.

After purchasing a Q2020 circuit breaker and finding that it cannot be fully inserted I had to purchase a Q2020NC which allows the switch to be fully inserted. Everything is identical except for where it clips onto the tire. Q2020 only allows partial insertion into the bus. Q2020NC is required for older panels. I believe that Q2020 can only be placed in certain places on the new panels.

Pros
  • Thermomagnetic circuit breaker
Cons
  • weak
