JJA36250U33X - 250 Amp Circuit Breaker

JJA36250U33X - 250 Amp Circuit Breaker

With the JJA36250U33X, the trip unit and connection setup tell much of the story. This 250A, three-pole PowerPacT J circuit breaker uses a MicroLogic 3.2 S electronic trip unit with LSI protection, rather than a thermal-magnetic trip configuration. The JJA36250U33X is built to last and is a practical choice for form, fit, and functional replacement when your electrical, trip-unit, mounting, and connection details match those of equipment already in service.

Key Features and Benefits

Where It Works Best

The JJA36250U33X is suitable for situations where the existing distribution equipment specifically calls for a 250A, three-pole PowerPacT J breaker with I-Line construction and MicroLogic 3.2 S electronic protection. For replacement work, those details matter more than simply finding another breaker marked 250A.
