Industrial motor starter

The SIEMENS 40DP32AA is a NEMA Size 1 magnetic contactor rated for 27 A inductive loads across three poles. It suits panel builders and maintenance teams who need a non-reversing starter for single-direction motor circuits in commercial or light-industrial panels.

Screw-terminal wiring and surface mounting

Power and control conductors land on screw terminals that accept standard ferrules or bare wire for secure, tool-friendly connections. The enclosure-less body mounts directly on a flat panel or DIN rail, measuring 4.31 in high by 4.25 in wide, so it fits tight rows without extra brackets.

Wide-range coil keeps pull-in steady

The coil operates from 110-120 V AC or 220-240 V AC, tolerating common supply fluctuations without chatter or drop-out. Normal operation is quiet, with only a faint mechanical click on engagement, and the coil draws minimal steady-state power once sealed in.

Questions about this item

What coil voltage range does the 40DP32AA contactor support?

The coil operates on 110-120 V AC or 220-240 V AC, covering both common control-circuit voltages.

What are the mounting dimensions and style for the 40DP32AA?

It measures 4.31 in tall by 4.25 in wide and uses surface-mount screw holes on a NEMA Size 1 frame.

How do you wire the power terminals on the 40DP32AA, and what mistake should be avoided?

Use the screw terminals for the three main poles and the single 1NO auxiliary; the error is forgetting to tighten every terminal to the specified torque.
