Schneider Electric (Square D) 8910DPA43V14 Contactor

The Schneider Electric (Square D) 8910DPA43V14 Contactor is a robust 3-pole definite purpose contactor engineered for reliable performance in HVACR and industrial motor control. Built with a 24V AC 50/60 Hz coil and rated for 40A inductive (50A resistive) loads, this Type DPA unit provides the switching capacity needed for high-demand equipment. As a direct replacement for V14970 and 42CF35AJAJT, it facilitates straightforward field retrofits without the need for extensive panel modifications.

This Square D 40 amp contactor features 3 NO contacts and supports multi-phase applications with a 600V AC maximum rating. It delivers substantial power-handling capabilities, including 25 HP at 575V AC and 20 HP at 460V AC for 3-phase systems, as well as 10 HP at 230V AC. The open enclosure design includes box lugs and quick-connect terminals to ensure secure electrical connections and reduced installation time, while the metal base plate permits stable panel mounting or integration with optional DIN track brackets.

Key Benefits

• Universal Compatibility: Functions as a direct drop-in for Furnas 42CF35AJAJT and Cutler Hammer C25DNF340T, streamlining inventory and field repairs.
• High Thermal Capacity: Rated for 50A resistive loads, ensuring durability in electric heating and refrigeration systems.
• Industrial Build Quality: Features double break contacts and a non-replaceable 24VAC control circuit coil for consistent switching cycles in motor control applications.
• Flexible Installation: Equipped with dual quick-connect terminals and standard box lugs for 40A+ configurations, and is compatible with snap-on auxiliary contact blocks.

Common Questions

Is the 8910DPA43V14 suitable for 1-phase motors?
Yes, while it is a 3-phase contactor, it can be utilized for single-phase applications by using the appropriate poles. It holds a rating of 3 HP at 115V and 7.5 HP at 230V for single-phase operation.

Can I add auxiliary contacts to this model?
This 40A Schneider contactor is compatible with 9999D series auxiliary contact modules, which snap onto the side to provide additional signals for control circuits.

What is the locked rotor amp (LRA) rating?
The unit is rated for 240A at 230V, 200A at 460V, and 160A at 575V, making it highly effective for managing the inrush current of commercial compressors and motors.
