Schneider Electric TA10D4S0504TPE TransferPacT 4P 50 A 400 V Rotary Controller Automatic Transfer Switch

The Schneider Electric TA10D4S0504TPE is a 4P TransferPacT automatic transfer switch rated for 50 A at 400 V AC, built on the 32-100 A TA10 frame. It switches a load between two AC supply sources through 3 contact positions with mechanical and electrical position indication, and its front rotary knob and selector switch give local manual control for automatic or manual operation.

Selection Notes

The rotary knob and selector switch give local manual control without a display, which keeps the front panel simpler than the LCD-controller version on the same TA10 frame; choose that LCD variant instead where remote status and alarm detail at the panel matter. The 50 A rating sits within the 32-100 A TA10 frame shared with the 32 A, 40 A, 63 A, 80 A siblings; pick a higher-current sibling if the connected load draws more than 50 A, since the enclosure and mounting dimensions stay identical across the frame. The 4-pole version additionally switches the neutral conductor, which matters when the two incoming sources do not share a common, solidly bonded neutral.

Applications

TransferPacT automatic transfer switches of this frame are used to change the power source for life-safety and continuity-critical loads such as fire-fighting equipment, smoke extraction fans, sprinkler pumps and emergency lighting in industrial and commercial buildings, data centers, healthcare facilities and transportation infrastructure, mounted inside a power distribution cabinet on DIN rail or plate.
