KT3150T - 150Amp Trip Unit

KT3150T - 150Amp Trip Unit

If KT3150T is the number on the trip unit you're trying to replace, the next step is making sure the rest of the details line up. The KT3150T is a 150-amp, three-pole T266 trip unit for compatible Series C J-K frame molded case circuit breaker applications. This is a trip unit accessory rather than a complete circuit breaker, an important distinction when sourcing parts for equipment already in service. If those requirements agree with the breaker assembly and equipment documentation, the KT3150T may be a suitable form, fit, and functional replacement. Properly matched, installed, and used within its specified application, it's built to last in the equipment it was designed to serve.

Key Features and Benefits

• 150-amp rating: Intended for compatible breaker assemblies calling for a 150A trip unit.

Where It Works Best

The KT3150T makes the most sense when you're maintaining an existing Series C J-K frame molded case circuit breaker assembly that calls for a 150A, three-pole T266 trip unit. In that situation, matching the component details matters more than simply finding another part with the same amperage.
