LAL36150 - 150 Amp Circuit Breaker

LAL36150 - 150 Amp Circuit Breaker

Replacing your circuit breaker in existing equipment usually comes down to one thing: making sure the details match. The LAL36150 is a 150-amp, 3-pole Type LA molded case circuit breaker with thermal-magnetic protection. This breaker uses a unit-mount configuration and comes with lugs on both the line and load sides. It also includes a Push-to-Trip feature for manually tripping the breaker without exposure to live parts. When properly selected, installed, and operated within its specified ratings, it's built to last in its intended application.

Key Features and Benefits

• 150A, 3-pole design: Suitable for compatible three-pole applications requiring a 150-amp breaker.
• Thermal-magnetic trip: Uses thermal sensing for overload conditions and magnetic sensing for short-circuit conditions.
• 600VAC rating: Rated for operation up to 600VAC in compatible equipment.
• Unit mount: Designed for equipment that uses this mounting arrangement.
• Line and load lugs: Provides lug connections on both sides of the breaker.
• Push-to-Trip: Allows manual tripping without exposure to live parts.

Material Compliance and Certifications

The LAL36150 is UL Listed and carries CSA and IEC certifications.

The supplied specifications did not include specific RoHS, REACH, or other material-compliance information. Those requirements should not be assumed. If a particular certification or material standard matters for the installation, check the product markings and applicable equipment documentation.

Where It Works Best

The LAL36150 is intended for compatible existing and legacy electrical equipment that calls for a 150A, 3-pole Type LA unit-mount circuit breaker with the corresponding electrical and physical specifications. For maintenance and replacement work, it gives you a straightforward set of ratings to compare with the breaker being removed.

Before installation, check more than the catalog number. Match the 150A rating, three poles, 600VAC rating, 22kA interrupting capacity, thermal-magnetic trip, unit-mount configuration, line and load lugs, AL400LA terminal identifier, and physical dimensions. If the breaker will be used on a DC circuit, confirm the 250VDC, 10kA rating as well.
