KT3125T - 125Amp Trip Unit Description
KT3125T - 125Amp Trip Unit
If KT3125T is the part number you're trying to match, it's worth knowing exactly what you're looking at. This is a 125-amp, three-pole T266 trip unit intended for compatible Series C J-K frame molded case circuit breaker applications. It is a trip unit accessory, not a complete circuit breaker, which matters when replacing a component in equipment already in service.

- Three-pole configuration: Matches breaker assemblies designed for the specified three-pole arrangement.
- T266 trip type: A key specification to check when identifying the correct replacement trip unit.
- J-K frame compatibility: Specified for use with compatible J-K frame equipment.
- Series C application: Designed for the stated Series C molded case circuit breaker family.
- Trip unit accessory: The KT3125T is a breaker component, not a complete molded case circuit breaker.

Where It Works Best
The KT3125T makes the most sense in existing or legacy Series C molded case circuit breaker equipment that calls for a 125A, three-pole T266 trip unit with a J-K frame designation.
For replacement work, put the old trip unit and the KT3125T specifications side by side. Confirm the catalog number where applicable, then check the 125A rating, T266 trip type, three-pole configuration, J-K frame, Series C designation, and dimensions. Verify details of the complete breaker assembly not included in the supplied specifications separately, rather than assuming them.
