KT3400T - 400Amp Trip Unit Description
KT3400T - 400Amp Trip Unit
The KT3400T is a 400-amp, three-pole T266 trip unit made for compatible Series C K-frame molded case circuit breaker applications. If you're replacing a trip unit in equipment already in service, match the full set of specifications—not just the 400A rating. Check the T266 trip designation, K-frame size, three-pole configuration, Series C identification, and the KT3400T catalog number against the existing component. Size is worth checking, too.
Key Features and Benefits
- 400A rating for applications requiring a 400-amp trip unit.
- Three-pole design for compatible three-pole breaker assemblies.
- T266 trip type provides an important reference when matching an existing component.
- Designed around the specified K-frame application.
- Series C identification helps narrow down compatibility with existing equipment.
- Supplied as a trip unit accessory, rather than a complete molded case circuit breaker.

Where It Works Best
The KT3400T makes the most sense when servicing existing or legacy Series C equipment that specifically requires a 400A, three-pole T266 trip unit for a K-frame application.
When checking a replacement, put the old component information next to the KT3400T specifications. Look for the KT3400T catalog number, T266 trip type, 400A rating, K frame, Series C designation, three-pole configuration, and physical dimensions. Those details give you a much better basis for determining compatibility than amperage alone.
