KA3100 - 100Amp Circuit Breaker

KA3100 - 100Amp Circuit Breaker

If you're looking at the KA3100, there are a few details worth checking against the breaker you already have. This model is rated 100 amps, has three poles, and uses a Type KA thermal-magnetic design with an interchangeable trip unit. The KA3100 is built to last, but choosing the right replacement still comes down to the details. Check the amperage, pole count, Type KA designation, trip arrangement, terminals, A.I.C. ratings, and dimensions against the existing installation before making the match.

Key Features and Benefits

• 100A rating with three poles gives you two of the first specifications to confirm when identifying a replacement.
• Type KA configuration provides another important compatibility checkpoint for existing and legacy equipment.
• Uses a thermal-magnetic design with an interchangeable trip unit.
• Rated at 40 °C according to the supplied product specifications.
• Load-side terminals are included, so you know what terminal arrangement is supplied with this model.
• A practical choice for form, fit, and functional replacement when the existing equipment calls for the same KA3100 specifications.
