KCL34125 - 125 Amp Circuit Breaker

KCL34125 - 125 Amp Circuit Breaker

A 125-amp rating is easy enough to match. The rest of the breaker deserves a closer look. The KCL34125 is a 3-pole, Type KCL molded-case circuit breaker with a thermal-magnetic configuration and line and load lugs. Those details matter when you're replacing a breaker in existing or legacy equipment, where a similar appearance doesn't necessarily mean a proper match. Properly selected, installed, and used within its stated ratings, it's built to last in the equipment it was designed to serve.

Key Features and Benefits

• 125A, 3-pole configuration: Clearly defined electrical characteristics for matching compatible equipment.
• Type KCL: An important identifier when checking an existing breaker or equipment requirements.
• Thermal-magnetic breaker: Matches applications calling for this particular trip configuration.
• Line and load lugs are included; both are supplied with the breaker.
• 60Hz, 40°C rated: Two additional details worth confirming before installation.

Material Compliance and Certifications

Certification and material compliance information wasn't provided in the available KCL34125 specifications. Because of that, specific UL, CSA, RoHS, REACH, or other listings shouldn't be assumed.

Where It Works Best

The KCL34125 is a sensible choice for replacement and maintenance work where the existing equipment calls for a 125A, 3-pole Type KCL thermal-magnetic molded-case circuit breaker with the corresponding electrical and physical characteristics.

For legacy equipment, it's worth checking more than the catalog number. Compare the 4.50"W x 8.00"L x 3.69"D dimensions, three-pole configuration, 125A rating, frequency, temperature rating, and the correct AIC value for the system voltage. You'll also want to confirm that the included line and load lugs meet the installation requirements.
