Description
Built for heavy-duty commercial power distribution, this 400A electronic trip breaker offers highly configurable protection parameters. It installs into Eaton Series C panelboards or motor control centers, though users must source the required rating plug and lug kits separately. The integrated LSG functions allow facility managers to fine-tune long-time, short-time, and ground fault settings, maximizing coordination across complex 3-phase electrical systems.Specifications

Product FAQs
7 answersDoes the LCLG3400F come with a rating plug and terminal lugs?
No. This unit is supplied as a frame with a factory-installed, non-interchangeable LSG trip unit. The required rating plug and terminal lug kits must be sourced separately.
Which terminal lug kit is compatible with the LCLG3400F circuit breaker?
The Eaton TA400LA1 terminal lug kit is compatible with LCL and LCLG frame molded case circuit breakers.
What rating plug is required for a 400A trip setting on this breaker?
You will need the Eaton 4LCL400 rating plug to configure this L-Frame Current Limit-R breaker for a 400A continuous current rating.
What protection parameters can be adjusted on the LCLG3400F trip unit?
The integrated solid-state electronic trip unit features LSG functions, allowing you to fine-tune Long-Time (overload), Short-Time (short circuit), and Ground Fault settings for precise coordination across your power distribution system.
How does the current-limiting feature of the LCLG3400F benefit my electrical system?
As a current-limiting breaker, it clears severe short circuits extremely fast, significantly reducing the peak let-through current and energy. This helps protect downstream conductors and sensitive equipment from thermal and magnetic stress during a fault.
Can I install the LCLG3400F in any Eaton panelboard?
No. This L-Frame breaker is specifically designed for Eaton Series C panelboards, switchboards, and motor control centers that are configured to accept L-Frame bolt-on devices.
Is the LCLG3400F suitable for high fault current applications?
Yes. With an interrupting capacity of 200kA at 480VAC, this current-limiting breaker is engineered for commercial and industrial environments with extremely high available fault currents.
