TJD422350 - 350Amp Circuit Breaker

TJD422350 - 350 Amp Circuit Breaker

The TJD422350 molded case circuit breaker is designed for dependable circuit protection in your commercial and industrial electrical distribution systems requiring a 350 amp, 2-pole breaker with a 22kA interrupting rating at 240VAC. Built as part of the trusted Q-Line family, this bolt-on circuit breaker features an internal common trip mechanism that helps you to disconnect both poles simultaneously during overloads or short circuits. Its HACR rating makes it suitable for heating, air conditioning, and refrigeration applications where consistent protection is essential. With included load-side lugs and a compact molded case design, the TJD422350 is commonly used in panelboards, switchboards, and distribution equipment where form, fit, and functional compatibility matter. These breakers were built for long-term service in demanding electrical environments and remain a practical solution for maintaining existing systems.
