Why contactors can't get smaller and what matters instead

Many people assume that in industrial EVs, smaller always equals better. For 30 to 40 years, contactor miniaturisation has delivered steady progress. But high-voltage contactors have now hit dimensional thresholds dictated by voltage, thermal management and arc suppression physics. These aren't engineering challenges waiting to be overcomethrough better design. They're physical constraints that define what's possible.
