999315 - 15 Amp Circuit Breaker

999315 - 15 Amp Circuit Breaker

The 999315 molded case circuit breaker is the kind of part you go looking for when you just need something that matches what’s already there. It’s a 15 amp, 3-pole breaker rated for 600VAC, built on the ML-1 (F-Frame)—a format that’s been used in plenty of commercial and industrial setups over the years. It uses a thermal-magnetic trip, so it handles overloads and short circuits the way you’d expect. Nothing fancy about it. It trips when it should, and that’s really the point. If you’re working in an existing panel or dealing with older equipment, having the right frame and rating saves time. This is one of those breakers that fits into place without turning the job into something bigger than it needs to be.
