CHT2020 - Duplex 20/20 Circuit Breaker

CHT2020 - Duplex 20/20 Circuit Breaker

The CHT2020 Eaton CH thermal magnetic circuit breaker is a 20/20 amp twin single-pole breaker designed for use in Eaton Type CH loadcenters. In practical terms, this is the kind of breaker you’ll find in residential and light commercial panels where two separate 20-amp circuits need to be handled in a single breaker space. It’s commonly used in systems that are already built around Eaton CH equipment, especially when panel space is limited but additional branch circuits are still required.

In the field, the CHT2020 is often used during maintenance or small system expansions where the goal is to keep everything consistent with the original panel design. Instead of adding extra hardware or changing the layout, this breaker fits directly into compatible Eaton CH loadcenters. That makes it a practical option when you’re working within an existing system and need a straightforward replacement or addition.

Each side of the breaker provides 20 amps of protection and operates independently within a shared twin design. Inside, it uses a thermal-magnetic trip mechanism that responds to both overload conditions and short circuits. That means it handles everyday electrical demand while still reacting quickly if a fault occurs.
