Square D JGL PowerPacT J-Frame 3-Pole Thermal Magnetic Circuit Breaker

Square D JGL PowerPacT J-Frame 3-Pole Thermal Magnetic Circuit Breaker

The Square D JGL PowerPacT J-Frame 3-Pole Thermal Magnetic Circuit Breaker protects electrical systems from overloads and short circuits with a rated operational voltage (Ue) of 600 V AC and an 18kA short-circuit interrupt rating, built to IEC 60947-3 standards. This lug-connected breaker is offered across a Motor FLA range of 150A to 225A, letting you match trip protection to your specific motor or feeder load while sharing the same thermal magnetic trip platform, 3-pole configuration, and 600V AC rating across every option. The thermal magnetic trip unit is rated for 80% continuous duty and is suitable for industrial and commercial distribution applications. Line and load lugs accept AWG 3/0...350 kcmil aluminum/copper terminals with a 25-25 N.m tightening torque range.
