Need to replace a tripped or faulty breaker in your panel? This is a Cutler-Hammer CH320. It's a 3-pole breaker, which means it controls three circuits or a 3-phase system. It's rated for 20 Amps at 240 Volts, and it has an interrupting capacity (AIC) of 10,000 amps (10kA) – that's its ability to safely stop a major short-circuit fault. Super important bit: this breaker is specifically made for type CH load centers (that's the brand/model of your electrical panel). Don't try to put it in a different brand's panel; it won't fit or be safe. Always make sure to turn off the main power before doing any electrical work, and if you're not 100% sure, call an electrician. This is a straightforward, no-fuss replacement breaker from a trusted brand like Cutler-Hammer.
