208 V AC three-pole contactor
The Siemens 40DP32AD is a NEMA Size 1 magnetic contactor rated for 27 A inductive loads at 208 V AC. It uses a three-pole, non-reversing design with a single normally-open auxiliary contact. The unit suits motor-starting panels and industrial control circuits that require a compact, surface-mounted switching device.
Screw terminals and surface mounting
Connections are made through screw terminals that accept standard ring or fork lugs for secure wiring. The enclosure carries no NEMA rating, so the contactor must be installed inside a suitable cabinet or panel. Overall dimensions are 4.31 in high by 4.25 in wide, allowing it to fit in typical starter enclosures with standard rail or back-plate mounting.
Verify coil voltage and load rating
Confirm that the control circuit supplies 208 V AC to match the coil before ordering. The contactor is rated for 27 A inductive current only and carries no resistive rating, so it must not be used for heating or lighting loads above that limit. Ensure the available auxiliary contact count meets your control logic requirements.

Questions about this item
What does the 208 V AC coil voltage mean for control-circuit compatibility?
The contactor operates on a 208 V AC control signal, so the pilot device or PLC output must supply that exact voltage to energise the coil reliably.
Will the 4.31 in height and 4.25 in width fit inside my existing panel cut-out?
The unit measures 4.31 in tall by 4.25 in wide; verify your enclosure has at least that clearance plus wiring space before mounting.
How do I wire the screw terminals correctly on the 3-pole main contacts and the 1NO auxiliary?
Strip each conductor to the terminal length, insert fully into the screw clamps, and torque to the manufacturer’s specification; the common error is under-tightening the auxiliary contact screw.
