KA36080 - 80 Amp Circuit Breaker

KA36080 - 80 Amp Circuit Breaker

The KA36080 is easy to narrow down when you know what to look for: 80 amps, three poles, Type KA, and an I-Line panelboard application. This molded case circuit breaker uses thermal-magnetic operation and is rated for 60 Hz and 40°C. The KA36080 is built to last and is best selected based on exact form, fit, and functional compatibility. Confirm the Type KA designation, 80A rating, three-pole arrangement, I-Line application, interrupting ratings, frequency, temperature rating, and dimensions against the existing equipment.

Key Features and Benefits

• 80A, three-pole configuration: Provides clear amperage and pole-count identifiers for replacement and compatibility checks.
• Type KA design: An important detail when matching the breaker to existing electrical equipment.
• For I-Line panelboards: Intended for installations that specifically call for this panelboard application.
• Thermal-magnetic operation: Uses the specified protection method for the KA36080.
• 60 Hz, 40°C rated: Two additional specifications that can help confirm the correct replacement.
• Well suited to replacement applications: A practical choice for compatible existing and legacy I-Line equipment requiring the same electrical and physical specifications.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material compliance or certification information was provided in the available KA36080 specifications. These certifications should not be assumed. Where a particular listing, approval, or compliance standard is required, verify documentation for the exact KA36080 part number before installation.

Where It Works Best

The KA36080 80A circuit breaker is intended for compatible I-Line panelboards that require a three-pole, Type KA molded-case circuit breaker with thermal-magnetic operation. It is particularly relevant when maintaining existing or legacy electrical equipment where matching the original breaker's physical and electrical characteristics is important.

For the best compatibility check, compare more than the amperage. Verify the Type KA designation, three-pole arrangement, 60 Hz frequency, 40°C rating, A.I.C. values, I-Line application, and 4.50" W × 10.50" L × 4.38 "D dimensions against the requirements of the existing installation.
