LA36125 - 125 Amp Circuit Breaker

LA36125 - 125 Amp Circuit Breaker

The LA36125 is a 125-amp, 3-pole molded-case circuit breaker for your compatible I-Line equipment. For replacement work, match these key details from the start: it uses a thermal-magnetic trip unit, is rated for 600VAC, and has a 22kA interrupting rating at 600VAC. Rather than relying on amperage alone, compare the catalog number, pole configuration, voltage, interrupting rating, mounting style, connections, and dimensions. When those details line up, the LA36125 can provide the form, fit, and function required for compatible existing and legacy electrical systems.

Key Features and Benefits

• 125A, 3-pole configuration for equipment requiring these specific electrical characteristics.
• Thermal-magnetic trip unit with a magnetic hold current of 625A and magnetic tripping current of 1250A.
• I-Line mounting provides the specified line-side connection for compatible equipment.
• AL400LA load-side lugs are included.
• HACR rated for applications where that designation is required.
• The operating handle moves to a center position after a trip, providing a visible trip indication.
• Clearly defined dimensions, mounting, and electrical ratings make it easier to check form, fit, and functional compatibility with existing equipment.

Material Compliance and Certifications

The LA36125 is UL Listed and CSA certified. The supplied product information also identifies IEC certification for the LA molded case circuit breaker family.

Where It Works Best

The LA36125 makes the most sense for existing and legacy I-Line electrical equipment where its 125A rating, three-pole configuration, 600VAC rating, thermal-magnetic trip technology, and physical dimensions match the equipment requirements. The supplied application information includes commercial and industrial buildings, construction applications, and control equipment panels.

When you're matching an existing breaker, put the specifications side by side. Check the LA36125 catalog number, I-Line mounting, 125A rating, three poles, system voltage, required interrupting capacity, and 11" x 6" x 5.84" footprint. You'll also want to confirm the connection arrangement. This breaker has an I-Line connection on the line side and AL400LA lugs on the load side.
