The Square D JGA36250 is a 250-amp, 3-pole, 600V PowerPact J-Frame molded case circuit breaker designed for heavy-duty feeder and branch circuit protection in industrial and commercial applications. The J-Frame series handles higher ampacities than the H-Frame, making it ideal for large motor loads, feeder circuits, and main distribution applications. With I-Line plug-in mounting, it integrates seamlessly into Square D I-Line switchboards and panelboards. The thermal-magnetic trip provides dependable LI protection, and the unit is 80% rated for continuous loading.
