I've never been a fan of the switch/breaker combo, if you are using these or plan on using them, you need to read the latest SAIB.

I like breaker switches. We've been changing out those W31 types for near 15 years. Just because those have always been junk is no reason to dis all breaker switches.
What are you replacing the W31's with? ...
Analysis of available service difficulty report (SDR) data indicates 2
percent of those analyzed failed by 2,000 cycles; 50 percent of those analyzed failed by 6,500 cycles, and 90 percent of those analyzed failed by 10,000 cycles.
Maybe carrying around spare switches is the answer.
