Square D JJL PowerPacT J-Frame 3-Pole Circuit Breaker, Thermal Magnetic, 600VAC

Square D JJL PowerPacT J-Frame 3-Pole Circuit Breaker, Thermal Magnetic, 600VAC

The Square D PowerPacT J-Frame is a 3-pole, thermal magnetic molded-case circuit breaker engineered for overload and short-circuit protection in commercial and industrial distribution systems. This family is available across a Motor FLA range of 175A to 200A, letting you match the breaker to the specific full-load-amperage demand of the connected motor or feeder while retaining the same 600VAC rating, 25kA interrupting capacity, and 80% continuous current application across the range. Every option terminates on line and load lugs sized for AWG 3/0...350 kcmil aluminum/copper conductors at 25-25 N.m torque, and every option is UL Listed, CSA Certified, and NOM Certified, built to IEC 60947-2/60947-3.
