KA361501021 - 150 Amp Circuit Breaker

KA361501021 - 150 Amp Circuit Breaker

The KA361501021 is a 150-amp, three-pole Type KA molded-case circuit breaker for compatible I-Line panelboards. If you're replacing a breaker in existing or legacy equipment, this part provides several concrete details to compare before installation: the Type KA designation, 150A rating, three-pole layout, physical size, and interrupting rating. The KA361501021 is built to last, while keeping the focus where it belongs for replacement work: matching the electrical ratings, I-Line application, Type KA configuration, and dimensions required by the equipment already in service.

Key Features and Benefits

• 150A, 3-pole configuration: Clearly defined amperage and pole count help simplify compatibility checks.
• Type KA design: Provides an important identifier when matching a replacement to existing equipment.
• For I-Line panelboards: Intended for compatible I-Line panelboard installations.
• Thermal-magnetic operation: Uses the specified thermal-magnetic circuit breaker design.
• 60 Hz rating: Provides another useful specification to verify against the existing electrical system.
• 40°C rated: Matches applications that call for this stated temperature rating.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for the KA361501021. These certifications should not be assumed from the product type or ratings alone. Where a particular listing or compliance standard is required, confirm it for this exact part number before installation.

Where It Works Best

The KA361501021 150A circuit breaker is best suited to compatible I-Line panelboards in existing and legacy electrical systems that require its specific Type KA characteristics. It can be particularly useful when the goal is a form-, fit-, and function-replacement rather than changing the existing equipment configuration.

For an accurate match, compare the 150A rating, three-pole, Type KA designation, thermal-magnetic design, 60 Hz and 40°C ratings, A.I.C. values, I-Line panelboard requirement, and physical dimensions with those of the breaker being replaced. Verifying the complete specification set helps ensure the KA361501021 is appropriate for the intended installation.
