HLC3400F - 400Amp Max. *Frame Only*

When you’re working on an existing electrical system, getting the frame configuration and ratings right matters. The Eaton HLC3400F is a 400A, three-pole molded case circuit breaker frame from Eaton’s Classic line, designed for applications requiring an HLC-type L frame. It carries a 600 Vac rating and a 35 kAIC interrupt rating at 480 Vac, with a T167 trip type. Just as important, the HLC3400F is supplied as a frame only, so it’s intended for installations where this particular frame configuration matches the requirements of the existing equipment.

Key Features and Benefits

• 400A rating for applications requiring a 400-amp molded case circuit breaker frame.

Material Compliance and Certifications

The HLC3400F is UL Listed, giving installers and maintenance professionals a clearly documented certification when UL-listed equipment is required for the application.

For replacement work, certification should be considered alongside the breaker’s other specifications. Check the frame, amperage, voltage, pole count, trip type, and interrupt rating against the existing equipment and application requirements. If a project has additional material or environmental compliance requirements, those requirements should be confirmed using the applicable product documentation.

Where It Works Best

The Eaton HLC3400F makes the most sense for existing commercial and industrial electrical distribution equipment that calls for an HLC, L-frame, three-pole molded-case circuit breaker configuration with matching ratings. It can be especially useful in maintenance and replacement situations where the goal is to maintain the correct form, fit, and function.
