KC34225 - 225 Amp Circuit Breaker

KC34225 - 225 Amp Circuit Breaker

Finding the right breaker for your existing panelboard often comes down to the details. The KC34225 is a 225-amp, 3-pole Type KC molded case circuit breaker for compatible I-Line panelboards. It has a thermal-magnetic configuration, operates at 60Hz, and carries a 40°C rating. For legacy equipment, amperage alone doesn't tell the whole story. The Type KC designation, pole count, dimensions, voltage, and AIC ratings must all match the panelboard's requirements. When those specifications match, the KC34225 can provide the form, fit, and function needed for replacement work.

Key Features and Benefits

• 225-amp rating: Intended for applications requiring a 225A breaker.
• Three poles: Provides the specified 3-pole configuration for compatible equipment.
• Thermal magnetic: Matches installations calling for this breaker configuration.
• Type KC: An important identifier when matching an existing breaker and panelboard.
• I-Line panelboard application: Intended for compatible I-Line panelboards.
• 60Hz, 40°C ratings: Useful specifications to confirm against the existing electrical system.

Material Compliance and Certifications

No specific material-compliance information or certification listings were included in the available KC34225 specifications. UL, CSA, RoHS, REACH, or other certifications should therefore not be assumed.

Where It Works Best

The KC34225 makes the most sense when you're maintaining or repairing a compatible I-Line panelboard that calls for this particular Type KC configuration. This is especially relevant with legacy equipment, where keeping the correct physical and electrical characteristics can be essential to the replacement process.

Start with the obvious details: KC34225, 225 amps, three poles, and Type KC. From there, check the items that are easier to overlook—the thermal-magnetic configuration, 60Hz frequency, 40°C rating, and applicable interrupting capacity. Physical measurements should also agree with the existing application.
