KA36090 - 90 Amp Circuit Breaker

KA36090 - 90 Amp Circuit Breaker

When you're tracking down a KA36090, the part number is only the beginning. The details that really help confirm the fit are its 90A rating, three-pole layout, Type KA designation, and I-Line panelboard application. The KA36090 is built to last, but the right replacement still comes down to compatibility. Check the Type KA designation, amperage, pole count, I-Line application, electrical ratings, and dimensions before installation.

Key Features and Benefits

• 90A, three-pole configuration: Gives you two of the first specifications to check when matching an existing breaker.
• Type KA construction: An important identifier when confirming compatibility with the breaker being replaced.
• Made for I-Line panelboards: The supplied specifications identify the KA36090 as compatible with I-Line panelboard applications.
• Thermal-magnetic protection: Uses a thermal-magnetic operating design.
• 60 Hz operation: Suitable for installations requiring the specified 60 Hz frequency.
• 40°C rated: Another key detail to compare with the existing installation.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other material-compliance and certification information was not provided for the KA36090. These certifications should not be assumed. If the installation requires a specific approval or compliance standard, verify it for this exact part number before use.

Where It Works Best

The KA36090 90A circuit breaker is intended for compatible I-Line panelboards where the existing installation calls for a three-pole Type KA molded-case circuit breaker with thermal-magnetic protection. It is especially relevant when maintaining existing or legacy equipment and the goal is to preserve the required form, fit, and electrical function.

Before making the final match, compare the KA36090 with the breaker being replaced and the panelboard requirements. Pay particular attention to the 90A rating, three poles, Type KA designation, I-Line application, 60 Hz frequency, A.I.C. ratings, 40°C rating, and physical dimensions. Those details help determine whether this is the correct breaker for the installation.
