LA36150 - 150 Amp Circuit Breaker

LA36150 - 150 Amp Circuit Breaker

The LA36150 is a 150-amp, 3-pole molded-case circuit breaker designed for compatible I-Line electrical equipment. If you're replacing a breaker already in service, compare several details side by side with the existing unit. For compatible existing and legacy equipment, the LA36150 can provide the required form, fit, and function when the electrical ratings and physical configuration match the application. Properly selected, professionally installed, and used within its specified ratings, it's built to last.

Key Features and Benefits

• 150A, 3-pole configuration for equipment requiring these specific electrical characteristics.
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection functions.
• I-Line mounting with an I-Line connection on the line side.
• AL400LA load-side lugs provide a defined terminal arrangement to compare with the existing installation.
• 750A magnetic hold current and 1500A magnetic tripping current.
• The operating handle moves to a center position after a trip, making the tripped condition visible at the breaker.
