KMB3B700 - 700Amp Circuit Breaker

KMB3B700 - 700Amp Circuit Breaker

At 700 amps, the KMB3B700 falls into a specific range, but amperage alone won't tell you whether it belongs in the equipment you're servicing. For a legacy installation, start with the KMB type and 700A rating, then confirm the three-pole configuration, footprint, system voltage, and required interrupting capacity. When the electrical and physical requirements align, the KMB3B700 may be suitable as a form-, fit-, and function-replacement in compatible existing equipment.

Key Features and Benefits

• 700-amp rating for compatible equipment requiring this specific current rating.
• The 3-pole configuration provides a clear reference point when identifying the correct breaker for an existing installation.
• The Type KMB molded case circuit breaker designation helps narrow compatibility beyond amperage alone.
• The 40°C temperature rating provides another key detail for confirming application requirements.
• Well suited to compatible legacy electrical equipment where the KMB type, ratings, dimensions, and installation requirements correspond.

Material Compliance and Certifications

The supplied specifications for the KMB3B700 included no specific certification or material-compliance information. Accordingly, do not assume UL listing, RoHS, REACH, or other certification and compliance status.

Where It Works Best

The KMB3B700 is best considered for existing and legacy electrical equipment that requires a 700A, 3-pole Type KMB molded case circuit breaker with matching physical and electrical characteristics.

For replacement work, place the existing breaker specifications next to those of the KMB3B700. Check the KMB type designation, 700A rating, three-pole configuration, 8.25"W x 14.50"L x 5.50"D dimensions, and the AIC requirement at the actual system voltage.
