JJL36250 - 250 Amp Circuit Breaker

Meet the JJL36250, a high-performance 250 Amp circuit breaker designed specifically for heavy-duty electrical systems. As part of the PowerPacT J-Frame line, this 3-pole breaker delivers dependable protection at 600V AC with a 25 kA breaking capacity—making it an excellent choice when you want serious, long-term reliability in commercial or industrial environments. Whether you’re installing new equipment or upgrading an existing panel, the JJL36250 gives you the performance you expect and the confidence you deserve.

Key Features and Benefits

• Advanced Thermal-Magnetic Trip Unit: The built-in thermal-magnetic mechanism ensures the breaker reacts precisely to both overloads and short-circuit events so your system stays safe and stable.
• Dual-Break Rotating Contacts: These contacts reduce peak current during fault conditions, helping extend the life of your wiring and downstream equipment.
• Push-to-Trip Button: For testing or maintenance, the integral push-to-trip feature gives you manual control, with zero hassle and no separate testing gear required.
• Scalable Upgrade-Friendly Design: Designed for forward compatibility, the JJL36250 accommodates future expansions or code-driven upgrades without needing a complete system overhaul.
• High Current Rating for Demanding Loads: With a full 250 Amps of continuous current handling, this breaker is built to tackle serious load centers, large motors, banked equipment or multi-tenant mains.
