Square D JJA PowerPacT J 3-Pole Circuit Breaker, 600VAC I-Line Thermal Magnetic

Square D JJA PowerPacT J 3-Pole Circuit Breaker, 600VAC, I-Line, Thermal Magnetic

The Square D PowerPacT J 3-Pole Circuit Breaker is a thermal magnetic molded-case breaker engineered to protect electrical systems from overloads and short circuits. This page covers the PowerPacT J breaker across its available Motor FLA ratings — 150A, 175A, 200A, and 225A — so you can match the exact rating your application requires. Every option shares the same core platform: 600VAC rated operational voltage (Ue), 25kA interrupt capacity, 750V rated insulation voltage (Ui), and an 8kV rated impulse withstand voltage (Uimp), making this breaker family well suited for commercial and industrial power distribution.

Key Features
