Square D PowerPact JJL36250T J-Frame 3P 250A Field-Interch TM
250A Frame | 250A | 3P | 100kA@240V, 65kA@480V, 25kA@600V | Thermal-Magnetic (Field-Interchangeable)
The PowerPact JJL36250T from Schneider Electric's Square D product line is a J-Frame 3-pole 250-amp circuit breaker designed for professional electrical installations and industrial systems. This MCCB delivers extra-high interrupting capacity of 100kA@240V, 65kA@480V, 25kA@600V at 600V AC / 250V DC for dependable overcurrent protection performance. Designed with field-interchangeable trip unit capability, this breaker allows on-site trip unit replacement without replacing the entire breaker frame, significantly reducing maintenance costs, inventory requirements, and system downtime. The TMD (Field-Interchangeable) trip unit provides reliable overcurrent protection with proven thermal overload and magnetic instantaneous response characteristics. Configured for unit mount installation, the JJL36250T utilizes lug (unit mount) connections with AL250JD Lug terminations designed for reliable conductor termination. The unit accommodates 3/0-350 kcmil Al/Cu conductors within compact overall dimensions of 5.90" H x 4.50" W x 3.63" D weighing ~12 lbs, optimizing installation density in electrical distribution equipment. UL 489 listed and CSA C22.2 No.5 certified, the JJL36250T meets IEC/EN 60947-2 international standards for global project specification and acceptance. Applications include feeder circuit protection, branch circuit protection, motor control center installations, panelboard and switchboard applications, and industrial power distribution systems requiring J-Frame frame-class protection capabilities. Backed by Schneider Electric's global expertise in power distribution solutions, the JJL36250T ensures dependable protection for critical electrical infrastructure with comprehensive factory warranty coverage and support.
