TJD422300WL - 300Amp Circuit Breaker

TJD422300WL - 300 Amp Circuit Breaker

The TJD422300WL molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems requiring a 300 amp, 2-pole configuration. Built as part of the trusted TJD Q-Line series, this breaker features an internal common trip mechanism that disconnects both poles simultaneously during overloads or short circuits, helping you to protect connected equipment and wiring from electrical damage. Its cable-in/cable-out lug-lug design allows for straightforward installation in compatible panelboards and switchgear applications, while the included line- and load-side lugs help simplify field setup. With a 22kA interrupting rating at 240VAC and HACR certification, the TJD422300WL is commonly used in HVAC systems, power distribution equipment, motor control applications, and other demanding electrical environments where reliable overcurrent protection is essential. Built for long service life and compatibility with existing systems, this breaker provides the form, fit, and function needed for maintaining or replacing installed equipment.
