CHT1520 - Duplex 15/20 Circuit Breaker

CHT1520 - Duplex 15/20 Circuit Breaker

The CHT1520 Eaton CH breaker is a 20/15-amp twin single-pole thermal-magnetic circuit breaker designed for Eaton Type CH load centers. In everyday electrical work, this is the kind of breaker you reach for when you need two separate circuits but don’t have extra room in the panel. It gives you flexibility without forcing changes to an already existing setup.

Most of the time, you’ll see the CHT1520 used in panels that are already installed and in service. Instead of reworking the layout or adding equipment, this breaker lets you fit two independent branch circuits into a single breaker space. It plugs directly into compatible Eaton CH loadcenters, so installation stays simple and consistent with the rest of the system.

On the inside, it uses a thermal magnetic trip system that responds to both overloads and short-circuit conditions. That means it handles the everyday load on a circuit and reacts quickly if something goes wrong electrically. Each side of the breaker works independently, giving you a 20-amp circuit on one side and a 15-amp circuit on the other.
