KT3225T - 225Amp Trip Unit

KT3225T - 225Amp Trip Unit

When you’re replacing a trip unit in equipment that’s already on the job, the KT3225T gives you several specific details to work from. It’s a 225-amp, three-pole T266 trip unit identified for compatible Series C J-K frame molded case circuit breaker applications. One distinction matters right away: the KT3225T is the trip unit itself, not a complete circuit breaker. That makes the existing assembly and its documentation an important part of the selection process.

Key Features and Benefits

• 225-amp rating: Suited to applications specifically calling for a 225A trip unit.
• Three-pole configuration: Matches compatible three-pole breaker assemblies.
• T266 trip type: A useful identifier when comparing the unit with an existing component.
• J-K frame: Specified for compatible J-K frame applications.
• Series C designation: Another key detail to check when sourcing a replacement for existing equipment.
• Trip unit accessory: This component is a trip unit and should not be confused with a complete molded case circuit breaker.
