LH36125 - 125 Amp Circuit Breaker

LH36125 - 125 Amp Circuit Breaker

Finding the right breaker for your existing I-Line installation means getting several details right. The LH36125 is a 125A, 3-pole molded case circuit breaker with thermal-magnetic protection and an I-Line mounting configuration. Rated for 600VAC, it has an interrupting rating of 25 kA at 600VAC. Each pole incorporates thermal sensing for overload conditions and magnetic sensing for short-circuit conditions.

Material Compliance and Certifications

The supplied manufacturer information identifies the LH36125 as UL Listed and CSA certified. The product description also states that LH molded case circuit breakers carry IEC certification and references UL 489 for the breaker family.

Where It Works Best

The LH36125 125A 3-pole circuit breaker is particularly suited to existing and legacy I-Line electrical distribution equipment that requires its specific combination of electrical protection, mounting, and connections. That's an important distinction. Matching 125 amps and three poles alone doesn't establish that another breaker will provide the same form, fit, and function.

When the 125A rating, three-pole arrangement, 600VAC rating, 25 kA interrupting capacity, LH thermal-magnetic characteristics, I-Line mounting, AL400LA load-side terminals, and physical dimensions correspond to the existing equipment requirements, the LH36125 can be evaluated as the correct form, fit, and functional replacement for the application.
