No. The LDC3600T57W ships without terminals, so you have to order the line and load lug or terminal kit for the L-frame separately. Plan on that before the shutdown window, because the breaker itself is a complete breaker (frame plus trip unit assembled), not a frame-only shell.

The LDC3600T57W is rated 100 kAIC at 480 Vac and 200 kAIC at 240 Vac. That puts it in the high interrupting LDC class of the L-frame, which is what you need where available fault current at the service or a large distribution board runs past what a standard L-frame handles.

LSIA means four adjustable protection functions in one trip unit: long delay, short delay, instantaneous, and ground fault alarm. That lets you set pickup and time bands to coordinate selectively with upstream and downstream devices, which a fixed thermal-magnetic L-frame cannot do. One setting interaction to know: choosing the long delay I4t response limits the short delay time to a flat response.

It carries a UL Listing. For an institutional or MRO spec, that plus the 600 Vac / 250 Vdc rating and the three-pole 600A frame is what goes on the submittal; download the Eaton spec sheet linked on the product for the full listing detail and enclosure data.

Published at 13 pounds, with height, width, and depth each listed at 8.25 inches. At that weight you are lifting it into position by hand but you want a second set of hands on a vertical mount, and you need roughly an 8-1/4 inch cube of clear volume in the enclosure before you add terminal kits and cable bending space.

Both are Series C L-frame molded case breakers, and the C suffix designates the high interrupting capacity version. On the LDC3600T57W that means 200 kAIC at 240 Vac and 100 kAIC at 480 Vac. If your fault current study calls for those numbers, the standard-interrupting L-frame will not satisfy it, and the frames are not interchangeable on rating alone.

Yes on both counts within its ratings: the LDC3600T57W is rated 50-60 Hz and carries a 250 Vdc rating alongside 600 Vac. That covers 50 Hz distribution and DC applications such as battery or drive circuits up to 250 volts.
