KB3225 - 225Amp Circuit Breaker

KB3225 - 225Amp Circuit Breaker

When your existing electrical system needs a replacement breaker, getting the details right matters. The KB3225 is a 225-amp, 3-pole Type KB thermal magnetic circuit breaker equipped with an interchangeable trip unit. Rather than relying on amperage or appearance alone, buyers can compare these specifications with the existing breaker and equipment requirements to determine whether the KB3225 provides the needed form, fit, and function. When correctly matched to the application, properly installed, and operated within its specified ratings, this breaker is built to last.

Key Features and Benefits

• 225A, 3-pole configuration for compatible equipment requiring these specific electrical characteristics.
• Thermal-magnetic circuit breaker design with an interchangeable trip unit.
• Type KB configuration for applications that require this breaker type and physical format.
• 40°C rated, providing another specification to verify when matching the breaker to existing equipment.
• Load-side terminals included, making the supplied terminal configuration clear before installation.
• Well suited to maintenance and replacement situations involving compatible legacy electrical systems where the KB3225 specifications match the original application.

Material Compliance and Certifications

Specific material-compliance information and certification listings were not provided in the available specifications for the KB3225. UL, CSA, RoHS, REACH, or other certification and compliance designations therefore should not be assumed without supporting documentation.

Where It Works Best

The KB3225 is best suited for compatible legacy electrical equipment requiring a 225A, 3-pole Type KB thermal-magnetic circuit breaker with an interchangeable trip unit. It is particularly relevant for maintenance and replacement work where preserving the required physical configuration and electrical characteristics is important.

A matching 225-amp rating by itself isn't enough to establish compatibility. Before using the KB3225 as a functional replacement, compare the complete part number, Type KB designation, three-pole configuration, interchangeable trip unit, voltage and AIC ratings, 40°C rating, physical dimensions, and load-side terminal requirements with the existing breaker and equipment specifications.
