Definite Purpose Magnetic Contactor, 120V AC, 3 P, Non-Reversing, 3 Phase, Quick Connect

The SQUARE D - 8910DPA43V02Y181 is a Definite Purpose Magnetic Contactor, an industrial electrical device designed to control the flow of power in heavy-duty applications. It operates by responding to electrical impulses, allowing or interrupting power supply based on the need. This tool is commonly used for managing and automating machinery operations in various sectors like HVAC, data processing, and manufacturing.

• Coil Voltage: The coil voltage refers to the specific voltage range required for this contactor to effectively engage or disengage its electrical circuit. For this model, it's rated at 120V AC.
• Depth: With a depth measurement of 3 inches, it indicates how far this contactor extends into its mounting surface or enclosure.
• Frequency: Rated for operation within the specified electrical cycle frequency of 50/60 Hz which may affect its compatibility with various power systems.
• Amps-Inductive & Resistive Load Capacity: This contactor is rated for a maximum current capacity of up to 40 A for inductive loads like motors or transformers and up to 50 A for resistive or heating loads. Exceeding these limits may result in overheating or damage.
• Horsepower Control Range: The horsepower control range varies based on the phase and voltage of your system (ranging from single-phase at 120V AC up to three-phase at 600V AC). This contactor is compatible with motor powers between minimums around approximately 3 hp and maximums near about approximately 20 hp.
• Poles & Contacts: Equipped with three poles that allow simultaneous switching of circuits and three normally open main contacts that remain open when not powered for versatile control over multiple circuits with varying degrees of power requirements
• Safety Standards: This contactor complies with multiple safety standards including CSA, REACH, RoHS, and it's UL Listed. Compliance does not guarantee quality or performance but indicates adherence to guidelines set by recognized regulatory bodies.
• Terminal Connection Type: Features a quick connect terminal connection type for easy installation into an electrical circuit.
