Siemens Industrial Controls 40DP32AF Contactor
The Siemens 40DP32AF is a heavy-duty NEMA rated size 1 DP contactor engineered for demanding HVACR and industrial motor control applications. This 3-pole definite purpose contactor features a 120V AC coil and is rated for 30 amp inductive loads, providing reliable switching for three-phase systems. The Class 40 frame is built with high-grade silver cadmium oxide contacts to ensure long electrical life and reduced pitting under high-inrush startup conditions. Designed for seamless integration into existing control panels, it includes box lug terminals for secure wire terminations and a compact footprint that simplifies retrofitting. This Siemens industrial control component is ideal for cycling compressors, pumps, and fan motors where durability and precise motor starter contactor performance are required. Its open-frame construction allows for maximum heat dissipation and easy inspection of the contact carrier assembly during routine maintenance cycles.
Key Benefits for Technicians:- NEMA Size 1 compatibility ensures the unit handles heavy-duty inductive loads without the premature failure common in lighter-duty alternatives.
- The 120V coil voltage aligns with standard commercial control circuits, eliminating the need for additional step-down transformers.
- Three-pole configuration provides simultaneous switching for all legs of a 3-phase power supply, protecting motor windings from unbalanced voltage.
- Equipped with dual-tension pressure plates to prevent wire pull-out and ensure consistent conductivity in high-vibration environments.
- The Class 40 series design allows for field-mountable auxiliary contacts if additional signaling or interlocking is required.
What is the maximum amperage rating for the 40DP32AF?
This contactor is rated for 30 Amps (FLA) for inductive loads and 40 Amps for resistive heating loads, making it suitable for a wide range of motor and heater applications.
Can this contactor replace a standard 2-pole unit?
While it can switch 2-pole loads, it is specifically designed for 3-phase equipment. Ensure your control circuit matches the 120V coil requirement before installation.
Does this unit include auxiliary contacts?
The base model features the standard 3-pole configuration; however, the Siemens Class 40 frame is designed to accept snap-on auxiliary contact blocks if your sequence of operations requires them.
