Schneider Electric TA63D3S5004TPE TransferPacT 3P 500 A 400 V Rotary Automatic Transfer Switch

The TA63D3S5004TPE is a Schneider Electric TransferPacT automatic transfer switch rated 500 A at 400 V AC, 3-pole, built on the 630 A frame and fitted with a rotary controller. It switches a load between two independent AC sources without an external controller, holding 500 A continuously at 60 degrees C ambient inside a distribution panel.

Selection Notes

The rotary controller on the TA63D3S5004TPE sets source priority and timers through a rotary/dip switch on the front, a simpler interface for panels where the switch position rarely needs reconfiguration. At 500 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 3-pole configuration switches the phase conductors only, with the neutral left solid, 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.
