KM3F800 - 800Amp Max. *Frame Only*

KM3F800 - 800Amp Max. *Frame Only*

The KM3F800 is an 800-amp, 3-pole Type KM3 molded case circuit breaker frame only, using the specified Type ET 800 Ampere "KM" Frame. That frame-only detail matters. If you're replacing parts in existing equipment, confirm exactly what the installation requires rather than treating this as a complete breaker assembly. Before deciding whether it's the " right fit," compare the part number, KM3 type, 800A frame, three-pole arrangement, dimensions, voltage, and required interrupting rating with the equipment you're servicing. When those details match—and you confirm the necessary compatible components—the KM3F800 can be a good fit for retaining compatible legacy electrical equipment.

Key Features and Benefits

• 800A frame rating for equipment requiring the specified 800 Ampere KM frame.
• 3-pole configuration makes pole-count verification straightforward when matching an existing installation.
• Type KM3 identification helps confirm the correct breaker family and application.
• Frame only — intended for situations where the breaker frame itself is required rather than a complete assembled circuit breaker.
• Uses the specified Type ET 800 Ampere “KM” Frame.
• 40°C temperature specification provides another point to verify against existing equipment requirements.
• Well suited for compatible legacy applications when the required form, fit, electrical ratings, and associated components match.

Material Compliance and Certifications

No specific certifications or material-compliance information were included in the supplied specifications for the KM3F800. For that reason, do not assume UL, RoHS, REACH, or other compliance status.

Where It Works Best

The KM3F800 makes the most sense when you're maintaining legacy electrical equipment that calls for a Type KM3, 3-pole, 800 Ampere “KM” Frame with matching dimensions and electrical ratings.

Because this is FRAME ONLY, pay particular attention to what's already in the equipment and what additional components are required. Trip components, terminals or lugs, mounting details, accessories, and other assembly components weren't included in the supplied specifications, so confirm their compatibility separately.
