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

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

The Square D PowerPacT J 3-Pole Circuit Breaker (JDL) is a J-Frame molded-case breaker built to protect electrical systems from overloads and short circuits. This family is available with a Motor FLA rating from 175A to 250A, giving panel builders and electricians a single breaker platform that scales to the connected motor load. Every option in the family shares the same core design: 600VAC rated operation, thermal magnetic trip protection, an 80% rated continuous current design, a 14kA interrupt rating, and line/load lug terminations for a solid, code-compliant connection. Ideal for commercial and industrial distribution equipment requiring dependable overcurrent protection across a range of motor feeder sizes.

Key Features

• Motor FLA Range: Available from 175A to 250A to match the connected motor full-load amperage.
• Poles: 3-pole configuration for three-phase distribution circuits.
• Voltage Rating: 600VAC rated operational voltage (Ue) per IEC 60947-3, constant across the family.
