JJL36225 - 225 Amp Circuit Breaker

JJL36225 - 225 Amp Circuit Breaker

Protect your electrical infrastructure with confidence using this high-performance circuit breaker. The JJL36225 is a 225 A, 3-pole, 600 VAC unit built to safeguard your system from overloads and short-circuit events. With a 25 kA breaking capacity at 600 VAC (and higher ratings at lower voltages), this breaker is engineered for demanding applications. It uses proven thermal-magnetic trip technology and dual-break rotating contacts—features that help maintain system stability by reducing peak currents during fault conditions. Whether you’re outfitting a commercial building, industrial plant, or utility system, this unit offers reliable protection, flexible installation, and the assurance of full compliance with major standards.

Key Features and Benefits

• High interrupting capacity: Rated at 25 kA at 600 VAC (and up to 100 kA at 240 VAC) for superior fault protection and peace of mind in critical applications.
• Thermal-magnetic trip mechanism: Combines overload (thermal) and short-circuit (magnetic) protection in one device for reliable circuit defence.
• Dual-break rotating contacts: Designed to reduce peak current during short-circuit events, which helps improve system longevity and reduces stress on components.
• Flexible installation options: Suited for both unit-mount and I-Line constructions; offers line- and load-side lugs for versatile wiring configurations.
• Environmentally conscious design: Manufactured in compliance with RoHS and REACh regulations, and incorporating recycled packaging components.

Where It Works Best

• If you’re managing complex electrical distribution in industrial, commercial or utility settings, the JJL36225 shines as a go-to solution. It’s particularly well-suited for equipment rooms, large panelboards, switchboards or any application where dependable, high-capacity protection is non-negotiable. Because it handles high fault-level interrupting, it’s ideal for facilities with heavy motor loads, large transformers or fluctuating electrical demands—anywhere the margin for error is slim.
