KM3B600 - 600Amp Circuit Breaker Description
KM3B600 - 600Amp Circuit Breaker
The KM3B600 is a 600-amp, 3-pole molded case circuit breaker with a Type KM3 designation and Type ET 800 Ampere "KM" Frame. If you're trying to match one to equipment that's already in service, there are a few numbers you'll want to put side by side with the existing breaker. When properly matched to the equipment, installed correctly, and kept within its specified ratings, the KM3B600 is built to last in the service it was designed for.
Key Features and Benefits
- 600 Amp rating for equipment designed around this specific current rating.
- 3-pole configuration for applications requiring three poles.
- Type KM3 molded case circuit breaker.
- Uses the specified Type ET 800 Ampere "KM" Frame.
- Interrupting capacity is 22 kA at 600VAC.
- 40°C temperature specification gives you another useful detail to compare with the existing application.
- A sensible choice to evaluate for legacy electrical equipment where the KM3 type, frame, amperage, poles, dimensions, and electrical ratings match.

Where It Works Best
The KM3B600 makes the most sense in existing and legacy electrical equipment that calls for a 600A, 3-pole Type KM3 molded case circuit breaker with the specified KM frame and matching electrical characteristics.
Before settling on a replacement, take a close look at the breaker you're removing. Does the KM3 type match? Is it a 600A, 3-pole unit? Does the 9.00" W x 15.50 "L x 4.00 "D footprint work with the equipment? Then check the interrupting rating at the actual system voltage. These details help establish whether the KM3B600 provides the required form, fit, and function.
