KC34150 - 150 Amp Circuit Breaker

KC34150 - 150 Amp Circuit Breaker

The KC34150 is the kind of breaker where the details really count. It's a 150-amp, 3-pole Type KC molded-case circuit breaker with a thermal-magnetic trip design, intended for compatible I-Line panelboards. If you're replacing a breaker in a legacy installation, don't stop at the 150A rating or a similar-looking case. Compare the complete part number, Type KC configuration, pole count, interrupting ratings, dimensions, and panelboard requirements with the breaker already in service.

Key Features and Benefits

• 150 amps and three poles: Straightforward electrical specifications for matching the breaker to the required application.
• Thermal-magnetic trip design: Provides the trip configuration specified for the KC34150.
• Type KC molded case circuit breaker: The KC designation is a key detail when checking compatibility with existing equipment.
• Designed for I-Line panelboards: Intended for compatible panelboard applications requiring this breaker configuration.
• 60Hz, 40°C ratings: Two additional specifications worth confirming when matching an existing breaker.

Material Compliance and Certifications

Need the KC34150 to satisfy a particular certification or material-compliance requirement? The supplied specifications don't provide enough information to confirm one.

Specific certification and material-compliance information was not provided for the KC34150, so UL, CSA, RoHS, REACH, or other listings and compliance designations should not be assumed.

Where It Works Best

The KC34150 is intended for compatible I-Line panelboard applications requiring a 150A, 3-pole Type KC thermal-magnetic molded-case circuit breaker with the stated electrical and physical characteristics. It's particularly relevant when maintaining legacy equipment, where the goal is to keep the correct form, fit, and function.
