TJJ436225WL - 225Amp Circuit Breaker

TJJ436225WL - 225 Amp Circuit Breaker

The TJJ436225WL molded case circuit breaker is built for your applications where dependable circuit protection and equipment compatibility matter. Designed as part of the Q-Line series, this 225 amp, 3-pole breaker is commonly used in commercial and industrial power distribution systems that require steady, day-to-day performance.

This breaker uses a thermal magnetic trip unit, which helps respond to both overload conditions and short circuits. The internal common trip feature allows all poles to disconnect together during a fault, helping protect connected equipment in three-phase systems. Its lug-lug design allows for cable-in/cable-out installation, and both line-side and load-side lugs are included for added convenience during setup.

With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, the TJJ436225WL fits a wide range of electrical distribution applications. It is also HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment installations. Whether used in a panelboard, switchboard, or industrial distribution setup, this breaker is designed to provide the form, fit, and function needed for existing systems.

Built to last and made for demanding environments, the TJJ436225WL remains a practical solution for contractors, maintenance teams, and facility operators looking for reliable molded case circuit protection.
