LH36150 - 150 Amp Circuit Breaker

LH36150 - 150 Amp Circuit Breaker

When an existing I-Line installation calls for an LH36150, matching the catalog number is a strong starting point, but the details behind that number determine compatibility. The LH36150 is a 150A, 3-pole molded-case circuit breaker with thermal-magnetic trip technology and an I-Line mounting configuration. Manufacturer specifications identify a 25 kA interrupting rating at 600VAC, making voltage and available fault current important parts of the application check. Connection style matters, too. This breaker uses an I-Line connection on the line side and AL400LA lugs on the load side. Put those characteristics together with its amperage, three-pole arrangement, dimensions, and protection characteristics, and you have a much more useful picture of whether the breaker matches the existing equipment than amperage alone can provide.

Key Features and Benefits

• 150A, 3-pole molded case circuit breaker for compatible electrical distribution equipment

Material Compliance and Certifications

Manufacturer specifications identify the LH36150 as UL Listed and CSA certified. The supplied product information for the LH breaker family also identifies UL 489, CSA, and IEC certification.

Where It Works Best

The LH36150 150A 3-pole circuit breaker is best considered for existing and legacy I-Line electrical distribution equipment that specifically calls for this breaker configuration. Replacement work is where careful specification matching pays off. Two breakers can share the same amperage while differing in mounting, terminals, interrupting capacity, trip characteristics, or physical size.
