The Schneider Electric TA10D4L0324TPE is a TransferPacT automatic transfer switch (ATS) rated 32 A at 400 V AC, 50/60 Hz, with four poles. It is designed for changing the source of supply — typically between a mains feed and a backup generator — in commercial or light industrial panels. The PC class per IEC 60947-6-1 means it is a switching device for the transfer of loads between two sources, not a circuit breaker; overcurrent protection is handled upstream. The AC-33B utilization category covers mixed resistive and inductive loads including motors up to 32 A, which is the typical duty for an ATS feeding a building's essential services panel. The switch carries a short-time withstand current (Icw) of 5 kA for 0.1 s and a making capacity (Icm) of 15 kA alone, or 75 kA with an upstream protection circuit breaker at 400 V AC — so it can close onto a fault without welding contacts, provided the upstream breaker clears the fault within the withstand window.
Controls, display, and enclosure fit
The TA10D4L0324TPE has four push-buttons and an LCD screen for local control and status readout. It operates in automatic or manual mode, with a mechanical interlock between sources to prevent paralleling. Dimensions are 310 mm wide, 147 mm high, and 94 mm deep — a compact footprint for a 4-pole 32 A ATS. The three contact positions (source 1, source 2, OFF) are indicated mechanically, and the OFF position accepts a padlock for lockout/tagout. Signal contacts are configurable as 1 NO + 2 NC, 1 NC + 2 NO, or 2 NO, giving flexibility for remote status monitoring without an extra auxiliary block.
Environmental and isolation specs
The conventional free air thermal current (Ith) is 32 A at 60 °C, matching the operational current rating — no derating needed at typical panel ambient temperatures.
