The TA10D3S0324TPE is a Schneider Electric TransferPacT automatic transfer switch (ATS) rated 32 A at 400 V AC, 50/60 Hz, in a 3-pole configuration. It is classified as a PC-class transfer switch per IEC 60947-6-1, meaning it is designed for uninterrupted duty — it switches between normal and emergency sources without a neutral position, and it is suitable for isolation (the contacts provide visible gap indication). The AC-33B utilization category covers motor, resistive, and mixed loads up to 32 A, so it handles starting inrush from small motors and lighting banks on the same circuit. The short-time withstand rating (Icw) is 5 kA for 0.1 s, and the making capacity (Icm) reaches 15 kA for the switch-disconnector alone at 400 V AC, or 75 kA when paired with an upstream circuit breaker. That 75 kA figure tells you the ATS is designed to coordinate with a breaker in a high-fault panel — it will close into a fault without welding contacts, provided the upstream device clears within its ratings. The front face carries IP40 in auto mode (finger-safe against tools >1 mm), while the interior enclosure side is IP20 — suitable for a closed panel, not for washdown areas.
The connection pitch is 18 mm, and both upside and downside connections are screwed terminals — no special tooling needed for a panel builder. Overall dimensions: 310 mm wide, 147 mm high, 94 mm deep. The rotary knob selector switch offers automatic and manual operating modes. Mechanical interlocking between the normal and emergency contactors prevents both sources from closing simultaneously — a code requirement for any transfer switch feeding life-safety or critical process loads. A padlock provision on the OFF position allows lockout/tagout for maintenance.
What compliance documentation to expect
The switch is designed and tested to IEC 60947-6-1, the international standard for automatic transfer switches. The standard covers making, breaking, and short-circuit performance under the declared utilization categories. For a procurement pack, expect the manufacturer's declaration of conformity to the Low Voltage Directive (2014/35/EU) and the relevant harmonized standards. RoHS and REACH compliance documentation is typically included in the product technical file available from the supplier upon request.
