サーキットブレーカー（熱動式）

My old breaker kept tripping at random, but this replacement snapped right into the Drum Thickness Sander and has been holding steady through a full day of heavy use. The reset button feels much more positive than the original, giving a solid click. Exactly what I needed to get back to work.

Installed this in my Drum Thickness Sander in under a minute and it clicked right into place perfectly. The reset button has a much firmer feel than the old breaker, which gives me confidence it will last through heavy use.

Took a while to arrive, but the fit is spot-on for my drum sander and it reset exactly like the original did. Feels solid enough for the price, though I can't say I'm thrilled about paying extra for shipping on such a small part.
