DK2300W - 300Amp Circuit Breaker

DK2300W - 300Amp Circuit Breaker

The Eaton DK2300W Series C molded case circuit breaker is a dependable 300 Amp, 2-pole circuit breaker designed to protect electrical distribution systems from overloads and short circuits. Commonly found in commercial and industrial facilities, this breaker is an ideal replacement solution when maintaining existing Eaton Series C K-Frame installations where matching the original electrical ratings and physical configuration is critical.

Built with a T186 thermal-magnetic trip unit, the DK2300W responds to both sustained overload conditions and sudden fault events, helping safeguard connected equipment and electrical infrastructure. Its 300A rating, combined with a 65 kAIC interrupting capacity at 240 Vac, makes it suitable for demanding power distribution applications where reliable circuit protection is essential. The breaker also carries a 250 Vdc rating, providing flexibility for select DC applications.

Whether you're servicing a manufacturing facility, commercial building, institutional campus, or other industrial operation, the Eaton DK2300W helps keep existing electrical systems operating as designed. Supplied as a complete K-Frame breaker without terminals, it is intended for applications that require compatibility with Eaton Series C equipment. Like many Eaton molded case circuit breakers that continue to serve facilities for decades, the DK2300W was built for long-term use in demanding electrical environments.
