Product FAQs
8 answersWhat panelboards and switchboards is the CLDC3400T107W compatible with?
This Series C, L-Frame breaker is designed for use in Eaton and Cutler-Hammer panelboards, switchboards, and motor control centers that accept L-Frame breakers.
What does the LSIA trip function on the CLDC3400T107W indicate?
The LSIA designation means this electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous trip functions, along with a Ground Fault Alarm. This allows for precise curve shaping and system monitoring without initiating a ground fault trip.
Does the CLDC3400T107W come with lugs, and what type of mounting does it use?
This breaker features a bolt-on mounting style. While it is configured for lug terminals, L-Frame breakers often require specific lug kits (such as the TA400K or 3TA631LK series) depending on your wire size and conductor material. Verify your specific wire requirements before installation.
Can this breaker replace older Westinghouse or Cutler-Hammer L-Frame breakers?
Yes, the CLDC3400T107W is fully backward compatible with legacy Cutler-Hammer and Westinghouse Series C L-Frame installations, provided the system requires a 400A, 600V breaker with an electronic LSIA trip unit.
How does the electronic trip unit improve safety and coordination compared to thermal-magnetic breakers?
The electronic LSIA trip unit (OPTIM 1050) offers precise adjustability for long-time and short-time pickup and delay settings. This allows panel builders to tightly coordinate the breaker with downstream devices, reducing arc flash hazards and preventing nuisance tripping.
Can I adjust the trip settings on the CLDC3400T107W in the field?
Yes, the electronic trip unit features adjustable dials for the Long-Time, Short-Time, and Instantaneous settings. These must be configured by a qualified electrician to match the specific load and coordination requirements of your electrical system.
Is the CLDC3400T107W interchangeable with standard L-Frame thermal-magnetic breakers?
Yes, this electronic trip breaker shares the same physical dimensions and mounting footprint as standard Series C L-Frame thermal-magnetic breakers, making it a direct drop-in upgrade for existing L-Frame spaces.
What does the C in the CLDC prefix indicate compared to standard L-Frame breakers?
The C in CLDC indicates that this breaker is 100 percent rated. Unlike standard breakers that are rated for 80 percent continuous load, the CLDC3400T107W can carry its full 400A rating continuously when installed in an appropriately sized and ventilated enclosure.
