KA3150 - 150Amp Circuit Breaker Description
KA3150 - 150Amp Circuit Breaker
If you're sourcing a KA3150, there are a few details you'll want to put side by side with the breaker already in place. This model is rated 150 amps, has three poles, and uses a thermal-magnetic design with an interchangeable trip unit. The KA3150 is built to last, but the goal with a legacy replacement is simple—get the form, fit, ratings, trip arrangement, and connections right so the replacement matches what the existing equipment requires.
Key Features and Benefits
- 150A current rating for equipment requiring this specific amperage.
- The three-pole Type KA configuration provides clear identifiers for checking compatibility.
- Thermal-magnetic trip design matches systems calling for this type of circuit protection.
- Interchangeable trip unit is an important detail when comparing the KA3150 with an existing breaker.
- Load-side terminals are included, so the supplied connection arrangement is clearly defined.
- 40°C rated, matching applications where this temperature rating is specified.

Where It Works Best
The KA3150 150A 3-pole circuit breaker is suited to compatible existing and legacy electrical equipment that calls for a Type KA thermal-magnetic breaker with an interchangeable trip unit. It is especially straightforward to evaluate for replacement work because the amperage, pole count, interrupting ratings, dimensions, temperature rating, and load-side terminal configuration are all clearly specified.
