JDL36250 - 250 Amp Circuit Breaker

JDL36250 - 250 Amp Circuit Breaker

The JDL36250 three-pole circuit breaker from the PowerPacT J-Frame series is built to deliver dependable electrical protection across demanding industrial and commercial environments. Rated for 250 A and capable of handling fault currents up to 14 kA at 600 VAC, this breaker gives you a strong layer of safety for critical power systems. The thermal-magnetic trip unit ensures reliable overload and short-circuit protection, while features like dual-break rotating contacts minimise the stress on the device during fault events — so you get better longevity and fewer maintenance surprises. Environmentally compliant and globally certified, the JDL36250 makes a solid choice when performance and peace of mind matter.

Key Features and Benefits

• High Interruption Capacity: Rated at 14 kA at 600 VAC (18 kA at 480 VAC, 25 kA at 240 VAC) it stands ready to protect your system when trouble hits.
• Thermal-Magnetic Trip Unit: Offers fast, accurate response to overloads or short circuits, enhancing system safety and reducing downtime risk.
• Dual-Break Rotating Contacts: These reduce peak short-circuit current and the associated stress on the breaker, giving increased durability and fewer unexpected failures.
• Unit-Mount Design with Line & Load Lugs: Makes installation straightforward and accommodates a range of wiring configurations.
• Environmentally Compliant & Sustainable: Meets RoHS and REACh standards and is part of a design strategy supporting improved recyclability.
• Globally Certified for Safety: UL 489, CSA, NOM, IEC and CE certifications mean you’re covered in many international and domestic installations.
