Description
Built for industrial environments, the Eaton LCL3400F is a 3-pole, 400A molded case circuit breaker frame. This current-limiting L-Frame requires a separately purchased interchangeable trip unit. Designed for commercial and industrial use, it bolts into Eaton Pow-R-Line 4 panelboards, switchboards, and motor control centers. Rated for 200 kAIC at 480VAC, it provides superior short-circuit protection. The current-limiting design rapidly clears faults to minimize equipment damage.Specifications

Product FAQs
5 answersIs the LCL3400F a complete, ready-to-install circuit breaker?
No. The LCL3400F is a frame-only unit. While it includes a built-in electronic trip unit, it requires a compatible rating plug to set the continuous amperage before it can be placed into service.
What type of protection does the built-in trip unit provide?
The factory-installed, non-interchangeable electronic trip unit features LS functions, providing adjustable Long-Time and Short-Time delay protection for precise coordination in your electrical system.
What does it mean that the LCL3400F is a current-limiting breaker?
As a Current Limit-R breaker, it is designed to clear severe short circuits extremely fast. This rapid response reduces the peak let-through current and energy, minimizing thermal and mechanical stress on downstream equipment during a fault.
Which panelboards are compatible with this breaker frame?
This bolt-on L-frame breaker is specifically designed for installation in Eaton Pow-R-Line 4 panelboards, as well as compatible Eaton switchboards and motor control centers.
Can I swap the trip unit on the LCL3400F frame?
No, this specific frame is manufactured with a non-interchangeable electronic trip unit. However, the continuous current rating can still be adjusted by installing the appropriate rating plug for your application.
