DK2350Y - 350Amp Circuit Breaker

DK2350Y - 350Amp Circuit Breaker

The DK2350Y is a 350 Amp, 2-pole thermal magnetic circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical systems. When you're maintaining existing equipment or replacing a breaker in a compatible K-Frame installation, matching the original specifications is critical. This breaker is built to provide the proper form, fit, and function required for those applications while helping maintain the integrity of the electrical distribution system.

With a 65kA interrupting rating at 240VAC, the DK2350Y is designed to respond to overloads and short-circuit conditions before they can cause damage to connected equipment. Its thermal magnetic trip mechanism combines protection against both sustained overcurrents and sudden fault events, making it a common choice in power distribution systems where reliable circuit protection is essential.

Built to last and designed for compatibility with existing K-Frame systems, the DK2350Y is frequently used in manufacturing facilities, commercial buildings, institutional properties, and other demanding electrical environments. Whether you're replacing a failed unit during maintenance or supporting a larger equipment refurbishment project, this circuit breaker helps maintain the original protection characteristics and electrical ratings of the system.
