KB3100 - 100Amp Circuit Breaker

KB3100 - 100Amp Circuit Breaker

Finding the right breaker for your older electrical equipment usually comes down to the details. The KB3100 is a 100-amp, 3-pole Type KB thermal magnetic circuit breaker equipped with an interchangeable trip unit. For maintenance work on compatible legacy electrical equipment, the KB3100 may be a good fit when its specifications align with the breaker being replaced. It's built to last when correctly matched to the application, properly installed, and operated within its specified ratings.

Key Features and Benefits

• 100A, 3-pole configuration: Suited to compatible equipment requiring these specific electrical characteristics.
• Thermal magnetic design: Uses the thermal magnetic operating configuration specified for the KB3100.
• Interchangeable trip unit: An important feature to check when matching this breaker with an existing installation.
• Type KB configuration: Makes it easier to narrow the search when servicing equipment designed for this breaker type.
• Load-side terminals included: The breaker comes with the specified load-side terminals.
• A practical choice for legacy equipment: Particularly relevant when the job calls for maintaining the original form, fit, electrical ratings, and intended function.

Material Compliance and Certifications

No specific material-compliance information or certification listings were provided with the available specifications for the KB3100. UL, CSA, RoHS, REACH, or other certification and compliance designations therefore should not be assumed.

Where It Works Best

The KB3100 makes the most sense in compatible legacy electrical systems where the equipment calls for a 100A, 3-pole Type KB thermal magnetic circuit breaker with an interchangeable trip unit. In a replacement situation, matching the amperage is only one part of the job.

Check the complete part number and breaker type first. Then compare the pole configuration, AIC and voltage ratings, 40°C rating, physical dimensions, trip-unit configuration, and terminal requirements with the existing breaker and the equipment specifications. Those details help determine whether the KB3100 provides the required form, fit, and function for the application.
