Schneider Electric TA63D4L4004TPE TransferPacT Active 4P 400 A 400 V LCD Automatic Transfer Switch

The TA63D4L4004TPE is a Schneider Electric TransferPacT automatic transfer switch rated 400 A at 400 V AC, 4-pole, built on the 630 A frame and fitted with a LCD controller. It switches a load between two independent AC sources without an external controller, holding 400 A continuously at 60 degrees C ambient inside a distribution panel.

Selection Notes

The LCD controller on the TA63D4L4004TPE gives a local status and alarm display with push-button setting, which suits panels where an operator needs to read source and alarm status without opening the cover. At 400 A on a 630 A frame, the switch carries headroom above the present load, which lets the same frame cover a higher-current variant later without a mechanical change. The 4-pole configuration switches the neutral along with the phases, a choice that follows the earthing arrangement (TN-C-S vs TN-S) of the installation it serves. The 400 V AC rated Icm of 40 kA alone (330 kA backed by an upstream protective device) sets how much fault current the switch can close onto without welding its contacts, a figure to check against the available short-circuit current at the installation point.

Applications

TransferPacT automatic transfer switches of this type change the power source for life-safety and continuity loads such as fire-fighting equipment, smoke extraction fans, sprinkler pumps and emergency lighting, and are used in industrial and commercial buildings, data centers, healthcare facilities and transportation infrastructure where an uninterrupted supply between two sources is required.
