KT3250T - 250Amp Trip Unit Description
KT3250T - 250Amp Trip Unit
When you’re replacing a trip unit, 250 amps is only one of the numbers that needs to line up. The KT3250T is a 250A, three-pole T266 trip unit for compatible Series C J-K frame molded case circuit breaker applications. This is a trip unit accessory, not a complete circuit breaker. When the required form, fit, and function match, the KT3250T may suit compatible legacy equipment. Properly selected, installed, and used within its specified application, it’s built to last in the service it was designed for.
Key Features and Benefits
- 250A rating: Intended for applications requiring a 250-amp trip unit.
- Three-pole design: Matches equipment calling for a three-pole configuration.
- T266 trip type: A key identifier to check against the trip unit being replaced.
- J-K frame: Specified for compatible J-K frame applications.
- Series C: Another important detail when confirming suitability with existing equipment.
- Trip unit accessory: The KT3250T is a component of a molded case circuit breaker assembly, not a complete breaker.

Where It Works Best
The KT3250T makes the most sense when you’re servicing existing Series C equipment that requires a 250A, three-pole T266 trip unit for a J-K frame application.
Before installation, put the old component and the KT3250T specifications side by side. Check the catalog number, amperage, T266 trip type, pole count, J-K frame designation, Series C identification, and dimensions. Don’t determine compatibility from the 250A rating alone.
