TJJ436175WL - 175A Circuit Breaker

TJJ436175WL - 175A Circuit Breaker

The TJJ436175WL molded case circuit breaker is designed for your facilities that need dependable protection in everyday power distribution applications. Whether it’s installed in a commercial building, an HVAC setup, or industrial equipment, this 175 amp, 3-pole breaker helps you to protect electrical systems from overloads and short circuits while fitting into existing Type TJJ and Q-Line configurations. Because many maintenance teams are working with established electrical systems, compatibility matters as much as performance. This breaker features a cable-in/cable-out lug-lug design with included line and load lugs, making installation more straightforward when replacing or servicing existing equipment. The thermal magnetic trip unit reacts to both sustained overloads and sudden fault conditions, while the internal common trip mechanism disconnects all poles together when needed. Its interrupting capacity ratings of 22 kA at 600 VAC, 30 kA at 480 VAC, and 42 kA at 240 VAC make it suitable for a wide range of commercial and industrial applications. The compact, molded-case construction is designed for long-term use in demanding environments where consistent operation is important day after day.
