KMB3B800 - 800Amp Circuit Breaker Description
KMB3B800 - 800Amp Circuit Breaker
The KMB3B800 is an 800-amp, 3-pole Type KMB molded case circuit breaker for your electrical equipment that requires this specific combination of size and ratings. For replacement work, look at more than the 800A rating. If the KMB type, amperage, poles, dimensions, voltage, and required interrupting capacity all correspond, the KMB3B800 may be a suitable form, fit, and functional replacement for compatible legacy equipment.
Key Features and Benefits
- 800-amp rating for equipment requiring an 800A circuit breaker.
- Three-pole configuration for compatible three-pole applications.
- Type KMB molded case circuit breaker design provides a clear reference when matching existing equipment.
- The 40°C temperature rating gives you another key point to check against the existing installation.
- Well suited for consideration in legacy electrical equipment where the required form, fit, and ratings match.

Material Compliance and Certifications

Where It Works Best
The KMB3B800 makes the most sense when servicing existing or legacy equipment that specifically calls for an 800A, 3-pole Type KMB molded case circuit breaker with matching characteristics.
Before installation, put the specifications side by side with the breaker being replaced. Check the KMB type, 800A rating, three poles, physical dimensions, 40°C specification, system voltage, and required interrupting capacity. The AIC rating changes with voltage, so don't overlook that detail.
