LAL36150 - 150 Amp Circuit Breaker

LAL36150 - 150 Amp Circuit Breaker

The Square D LAL36150 150 Amp 3-Pole Circuit Breaker is built for heavy-duty protection in demanding electrical systems. With thermal-magnetic trip technology, this breaker delivers dependable overload and short-circuit defense across both AC and DC environments. Capable of handling up to 600 VAC and 250 VDC, it’s engineered for versatility, whether as part of a new installation or an upgrade to an existing setup. Its compact footprint and flexible mounting options make integration simpler—and its strong performance ensures your infrastructure stays safe and functional when it matters most.

Key Features and Benefits

• Precise protection you can count on: Combines thermal sensing (for slow overload) and magnetic sensing (for sudden short circuits) in each pole to respond quickly to electrical faults.
• Dual-voltage capability: Rated for both 600 VAC and 250 VDC, letting you use it across a broad range of electrical systems.
• Easy manual testing: Push-to-trip mechanism allows you to manually trip the unit without exposing live parts, enhancing safety during commissioning or maintenance.
• Flexible installation: Compact dimensions and multiple termination options allow mounting in tight spaces or retrofitting into existing panels without significant rework.
• Strong breaking performance: Delivers a high interrupting capacity—22 kA at 600 VAC and 10 kA at 250 VDC—making it suitable for facilities with significant fault current potential.
• Sustainable design: Complies with modern eco-standards (such as RoHS and REACH), and is built without mercury, PVC, or halogen for reduced environmental impact.
