Not sure how an equivalent to NEMA starters can last even a quarter the life of a rugged real deal quality starter ( A&B or Square D ) when the inferior IEC starters believe are only rated for 100,000 operations & guessing NEMA starters are a million.

Properly applied devices will have similar life, whether they are NEMA, definite purpose, or IEC style. The problem is engineering/designing for cost savings not long life.

IEC = Planned obsolescence.
Doesn't mean it's bad, just that you plan for it. Keep spares.

But since we tend to abuse our equipment, NEMA devices will last longer...IEC devices don't stand up to abuse.
However, you are 100% correct, IEC devices, when applied and used within their ratings are fine.
