Key Features of SA-4P-40A-208/240V:
- Current Rating: 40 Amps, which indicates the maximum current the contactor can handle.
- Voltage Rating: The contactor is designed to work with 208V or 240V AC systems, which are common voltage levels in many HVAC and industrial applications.
- Number of Poles: This is a 4-pole contactor, meaning it controls four separate electrical circuits or phases, which is typically used in multi-phase systems (such as 3-phase systems with a neutral or 4-phase systems).
- Coil Voltage: The coil voltage is typically rated to operate with 208/240V AC for energizing the contactor.
- Application: Primarily designed for HVAC systems, but can also be used for other industrial or commercial control systems that require high current switching at 208/240V AC.
Applications:
- HVAC Systems: It’s commonly used in controlling large electrical loads in HVAC systems, such as compressors, fans, and pumps.
- Industrial Applications: The contactor can be used in any industrial equipment requiring switching of high currents at 208/240V AC.
- Motor Control: Ideal for controlling motors, especially in HVAC, refrigeration, and other industrial machinery.
Benefits:
- Heavy Duty: This contactor is built to handle high loads, making it suitable for HVAC systems and other equipment requiring reliable switching of high current.
- 4-Pole Design: With 4 poles, it allows for more comprehensive control over multi-phase circuits, which is essential for 3-phase power systems with a neutral or other 4-phase configurations.
- Durability: HVACStar contactors are designed to withstand tough conditions, ensuring long-term performance in demanding environments.
- Efficient Operation: The design optimizes energy efficiency and minimizes the risk of overheating, which is especially important in HVAC applications.
Considerations:
- Coil Voltage Compatibility: Ensure that the coil voltage (208V or 240V) matches the supply voltage in your application.
- Auxiliary Contacts: Depending on your setup, you may need additional auxiliary contacts to monitor or control other system components.
- Overload Protection: Pair the contactor with proper overload relays to protect the equipment from overheating and prevent potential damage due to excessive current.https://store.unigulfsupply.com/product/contactor-sa-4p-40a-208-240v/
