The TA10D2L0803TPE is an 80 A automatic transfer switch from the TransferPacT range, rated for 230 V AC at 50/60 Hz. The 80 A figure is the uninterrupted rated operational current (Ie) and the conventional free-air thermal current (Ith) at 60 °C — meaning it carries 80 A continuously without derating in a 60 °C ambient. That is the number to match against your load's full-load amps; if your feeder is sized for 100 A, this switch is undersized. The 2-pole (2P) configuration switches both line conductors. The switch is class PC per IEC 60947-6-1, which means it is a transfer switch that can make, carry, and break currents under normal conditions but is not intended to interrupt fault currents — that is the job of the upstream overcurrent protective device. The AC-32B utilization category confirms it is rated for mixed resistive and inductive loads, typical of motor, lighting, and distribution circuits in commercial and light industrial buildings. Mechanical interlocking between the normal and emergency sources prevents both from closing simultaneously — a hard-wired safety requirement for any automatic transfer scheme.
Mounting and enclosure integration
The 18 mm connection pitch matches standard terminal-block spacing. Overall dimensions are 310 mm wide by 147 mm high by 94 mm deep — a compact footprint for a 2-pole 80 A transfer switch, but verify the enclosure depth allows the 94 mm plus wiring bend radius. Screwed connections on both the line and load sides; no special tooling needed. Front-face IP40 in auto mode; inside the enclosure it is IP20 in manual mode.
Withstand and making ratings — the fault-handling boundary
Rated short-time withstand current (Icw) is 5 kA for 0.1 s — the switch can hold that fault current until the upstream breaker clears. Rated short-circuit making capacity (Icm) is 15 kA at 400 V AC for the switch-disconnector alone; with an upstream protection circuit breaker, the making capacity rises to 75 kA at 400 V AC. That 75 kA figure assumes a properly coordinated upstream breaker; without it, the switch's own making capacity is 15 kA.
