LHL36225 - 225 Amp Circuit Breaker

LHL36225 - 225 Amp Circuit Breaker

The LHL36225 catalog number means more than its 225A rating. This is a 225A, 3-pole molded-case circuit breaker built around a thermal-magnetic trip unit and a unit-mount configuration. Instead of an I-Line connection, the breaker uses lugs on both the line and load sides, with AL400LA identified as the terminal configuration. Manufacturer data specifies an interrupting rating of 25 kA at 600 VAC and 50 kA at 250 VDC. Its magnetic characteristics are listed at 1,125A hold current and 2,250A tripping current. If you're standing in front of existing equipment trying to determine whether you've found the right breaker, those are the details worth paying attention to.

Material Compliance and Certifications

Manufacturer information supplied for the LHL36225 identifies the breaker as UL Listed and lists CSA and IEC certifications. These are useful specifications when an existing installation requires documented certification.

Where It Works Best

The LHL36225 225A 3-pole circuit breaker is particularly relevant when you're maintaining existing or legacy electrical distribution equipment that uses this unit-mounted, lug-connected breaker style.

One detail can narrow the search quickly: both sides use lugs. The LHL36225 has an AL400LA terminal configuration on a unit-mount breaker. That makes it mechanically different from an LH breaker that uses an I-Line connection, even if some of the numbers on the label look familiar.
