JJL36150 - 150 Amp Circuit Breaker

JJL36150 - 150 Amp Circuit Breaker

The Schneider Electric JJL36150 PowerPact J-Frame molded-case circuit breaker brings high performance protection to commercial and industrial electrical systems without the fuss. Rated at 150 amps and designed for up to 600 VAC operation, this three-pole unit offers strong protection against overloads and short circuits, while simplifying installation. Inside its compact housing, dual-break rotating contacts help limit peak fault current, and the thermal-magnetic trip unit gives you trusted performance under demanding conditions. Whether you’re retrofitting an existing panel or building out a new infrastructure, the JJL36150 delivers dependable switching, safety, and flexibility.

Key Features and Benefits

• High interrupt capacity: Handles up to 25 kA at 600 VAC (with higher ratings at lower voltages), giving you confidence in heavy-duty environments.
• Thermal-magnetic trip unit: Responds reliably to both overloads and short circuits, preserving system integrity and reducing downtime.
• Dual-break rotating contacts: Helps reduce peak current during fault events, which means less stress on your wiring and components—and improved safety.
• Unit-mount with lugs on both line and load sides: Makes installation straightforward and wiring more flexible—ideal for tight panel spaces or retrofit jobs.
• Designed for future flexibility: With proven standards compliance and a manufacturing pedigree, this breaker supports scalable electrical infrastructure with peace of mind.
