KA36070 - 70 Amp Circuit Breaker

KA36070 - 70 Amp Circuit Breaker

Working with an I-Line panelboard and trying to pin down the right replacement breaker? The KA36070 has several identifiers that make the compatibility check easier. There's also the physical fit to consider: the KA36070 measures 4.50 inches wide × 10.50 inches long × 4.38 inches deep. Those dimensions are especially useful when you're working with existing or legacy equipment where the available space and breaker arrangement are already established. The KA36070 is built to last, but compatibility still depends on the specifics. Compare the Type KA designation, amperage, pole count, I-Line panelboard requirement, A.I.C. ratings, frequency, temperature rating, and dimensions to those of the breaker being replaced.

Key Features and Benefits

• 70A, three-pole design: Gives you two essential specifications to confirm right away when checking a replacement.
• Type KA construction: Helps identify the breaker configuration required by the existing installation.
• Made for I-Line panelboards: The intended panelboard application is clearly specified, reducing the guesswork in compatibility checks.
• Thermal-magnetic operation: Uses the protection method specified for the KA36070.
• 60 Hz rating: Provides another important electrical specification to compare with the existing system.
• 40°C rated: Matches installations calling for this stated temperature rating.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance information was not included in the supplied specifications for the KA36070. These approvals should not be assumed. If a particular certification or standard is required for the installation, verify the documentation for the exact KA36070 part number before use.

Where It Works Best

The KA36070 70A circuit breaker is intended for compatible I-Line panelboards, making it relevant to existing and legacy installations that require a three-pole Type KA molded-case circuit breaker with thermal-magnetic operation. Rather than relying on amperage alone, the part can be checked against several concrete identifiers—including its 60 Hz rating, A.I.C. values, 40°C rating, and physical dimensions.
