KC34175 - 175 Amp Circuit Breaker

KC34175 - 175 Amp Circuit Breaker

When you're matching a breaker for existing electrical equipment, the 175-amp rating is only the beginning of the checklist. The KC34175 is a 3-pole, 175A Type KC molded-case circuit breaker with a thermal-magnetic trip configuration, intended for compatible I-Line panelboards. Rather than choosing by amperage or appearance alone, check the complete part number, Type KC designation, pole count, AIC requirements, dimensions, and panelboard configuration. When those characteristics correspond with the existing application, the KC34175 can provide the required form, fit, and function for compatible legacy equipment.

Key Features and Benefits

• 175A, 3-pole configuration: Clearly defined amperage and pole count make it easier to compare the KC34175 with the requirements of an existing installation.
• Thermal-magnetic operation: Uses the thermal-magnetic trip configuration specified for this breaker.
• Type KC molded case design: An important identification point when matching a breaker to compatible equipment.
• For I-Line panelboards: Intended for compatible panelboard applications requiring this particular breaker configuration.
• 60 Hz and 40 °C ratings: Additional operating specifications to include in a complete compatibility check.

Material Compliance and Certifications

If your facility or project requires a specific listing or material compliance standard, that detail should be verified separately. Specific certification and material-compliance information was not included in the supplied KC34175 specifications. Accordingly, UL, CSA, RoHS, REACH, or other certifications and compliance designations should not be assumed.

Where It Works Best

The KC34175 175A 3-pole circuit breaker is best suited for compatible I-Line panelboards and legacy electrical equipment that call for the corresponding Type KC molded-case configuration. Replacement situations are where the details become especially important. A breaker can have the correct amperage yet still differ in dimensions, interrupting capacity, pole arrangement, or equipment compatibility.
