KT3175T - 175Amp Trip Unit

KT3175T - 175Amp Trip Unit

If KT3175T is the part number you're trying to replace, compare a few details side by side with the existing component before deciding. This is a 175-amp, three-pole T266 trip unit for compatible Series C J-K frame molded case circuit breaker assemblies. When those details match the breaker and equipment requirements, the KT3175T may be a suitable form-, fit-, and function-replacement. Properly selected, installed, and used in its specified application, it's built to last in the equipment it was designed to serve.

Key Features and Benefits

• 175-amp rating: Made for compatible breaker assemblies that call for a 175A trip unit.

Where It Works Best

The KT3175T makes the most sense in existing and legacy electrical equipment using a compatible Series C J-K frame molded case circuit breaker assembly that requires a 175A, three-pole T266 trip unit.

For replacement work, start with the catalog number, but don't rely on that detail alone. Confirm the T266 trip type, 175A rating, J-K frame, Series C designation, three-pole configuration, and dimensions against the existing component and equipment requirements.
