KA36250 - 250 Amp Circuit Breaker

KA36250 - 250 Amp Circuit Breaker

When you're tracking down a KA36250 for an existing I-Line panelboard, the part number is only the beginning. You'll want the electrical ratings and physical size to line up as well. This 250-amp, three-pole Type KA molded-case circuit breaker uses thermal-magnetic protection and is specified for 60 Hz operation with a 40°C rating. The KA36250 is built to last, but compatibility still comes first. Check the Type KA designation, amperage, pole count, I-Line panelboard requirement, A.I.C. ratings, frequency, temperature rating, and dimensions against the breaker being replaced.

Key Features and Benefits

• 250A, three-pole design: Gives you two of the first specifications to check when identifying the correct replacement.
• Type KA configuration: Helps narrow compatibility with existing equipment that specifically calls for Type KA.
• Made for I-Line panelboards: Intended for use with compatible I-Line panelboard installations.
• Thermal-magnetic protection: Uses the specified thermal-magnetic operating design.
• 60 Hz frequency: Provides another important electrical specification to confirm against the installation.
• 40°C rated: Matches applications requiring the specified 40°C rating.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification information was provided for the KA36250. These certifications should not be assumed. Where a particular certification or standard is required, confirm it for the exact KA36250 part number before installation.

Where It Works Best

The KA36250 circuit breaker is intended for compatible I-Line panelboards. It is particularly relevant when maintaining existing or legacy electrical equipment that requires a 250A, three-pole Type KA molded-case circuit breaker.

Before making the final selection, compare more than the amp rating. Check the Type KA designation, three-pole arrangement, thermal-magnetic protection, 60 Hz frequency, 40°C rating, interrupting capacities, I-Line compatibility, and physical dimensions against the existing installation. That gives you a much clearer way to determine whether the KA36250 provides the required form, fit, and function.
