KC34110 - 110 Amp Circuit Breaker

KC34110 - 110 Amp Circuit Breaker

If you're looking for a KC34110 circuit breaker, chances are you're trying to match a fairly specific piece of existing equipment. The KC34110 is a 110-amp, 3-pole Type KC molded-case circuit breaker with a thermal-magnetic trip design, designed for compatible I-Line panelboard applications. With older electrical equipment, finding the right breaker isn't simply a matter of matching 110 amps or finding something that looks similar. The part number, Type KC configuration, number of poles, interrupting ratings, dimensions, and panelboard requirements all need to line up with the application.

Key Features and Benefits

• 110-amp rating: Suited to compatible applications specifically calling for a 110A breaker.
• Three poles: Provides the required configuration for equipment designed around a 3-pole breaker.
• Thermal magnetic design: Matches systems that require thermal-magnetic circuit protection.
• Type KC molded case construction: A key detail to confirm when identifying a replacement for existing equipment.
• I-Line panelboard application: Intended for compatible I-Line panelboards.
• 60Hz, 40°C ratings: Two additional specifications to check against the installation requirements.

Material Compliance and Certifications

No specific material-compliance information or certification listings were included in the available specifications for the KC34110. For that reason, UL, CSA, RoHS, REACH, or other certifications should not be assumed from the part number or specifications alone.

Where It Works Best

The KC34110 makes the most sense when you're maintaining a compatible I-Line panelboard or legacy electrical system that already calls for the characteristics of this Type KC breaker.

Before treating it as a replacement, work through the match carefully. Confirm the KC34110 part number, then check the 110A rating and three-pole configuration. Make sure the application requires a thermal-magnetic molded-case circuit breaker and that the specified 65k AIC at 480VAC or 100k AIC at 240VAC rating is appropriate for the system. The 60Hz frequency, 40°C rating, and 4.50"W x 10.50"L x 4.38"D dimensions should also agree with the equipment requirements.
