Siemens 40DP32AA Contactor

Siemens US2:40DP32AA is a NEMA Size 1, non-reversing three‑pole contactor intended as a motor starter for three‑phase circuit switching. It uses a dual‑voltage coil that can be energized from 110–120 V or 220–240 V AC at 60 Hz, enabling flexible control from common industrial power sources. The high‑voltage side is rated for 27 A and includes a normally open auxiliary contact in a 3‑wire configuration, suitable for basic control logic integration. This unit is specified with an open (non‑enclosed) NEMA enclosure and is a non‑combination type, designed for mounting in control panels or open‑panel installations. The 40DP32AA designation identifies a 3‑pole, Size 1 DP contactor in Siemens’ line of motor starters, delivering reliable, compact three‑phase switching for light to medium‑duty motors.
