Allen Bradley 509-A0D Non-Reversing Full Voltage Starter 18 A 600VAC

115-120V 50/60Hz COIL

The Allen-Bradley 509-A0D Series B NEMA Size 0 Motor Starter is a part of the Allen-Bradley 509 series of motor starters, which are used to control and protect motors in industrial applications. The “Series B” refers to a specific version or revision of this product. Below are some key features and details of the 509-A0D Series B NEMA Size 0 Motor Starter:

Key Features:

1. NEMA Size 0:

   • NEMA Size 0 is a classification for the motor starter’s physical size. This size is typically used for smaller motors with lower power ratings.
   • The NEMA classification ensures compatibility with a range of motor applications that need protection from overloads and short circuits.

2. Motor Protection:

   • The starter is designed to provide overcurrent protection and thermal overload protection for motors. This helps to prevent damage due to excessive current or prolonged overload conditions.

3. Motor Control:

   • The 509-A0D motor starter can be used to start and stop electric motors. It typically comes with a contactor (electromagnetic switch) that controls the power to the motor and can include an overload relay to protect the motor.

4. Magnetic Contactor:

   • The motor starter includes a magnetic contactor that is responsible for the actual switching of the motor circuit. The contactor is energized by a control signal, typically from a control panel or remote switch.

5. Frame Size:

   • This motor starter is classified under NEMA Size 0, meaning it is compact and typically used in applications requiring smaller starters, such as motors up to 1-3 horsepower (depending on voltage and type of motor).

6. Series B Revision:

   • The “Series B” designation indicates that this model is an updated version of the original 509 motor starter, with potential improvements in design, materials, or compliance with updated safety or efficiency standards.

7. Enclosure Ratings:

   • Depending on the specific variant, the starter may be available in various enclosure types (e.g., open or enclosed), which determine the level of environmental protection (e.g., protection against dust or water ingress).

8. Compatibility:

   • Designed to work with Allen-Bradley components, but it may also be compatible with other NEMA-rated devices and systems.

Applications:

• Industrial Automation: It is commonly used in manufacturing processes and assembly lines where small to medium-sized motors need to be controlled and protected.
• HVAC Systems: This motor starter may be used to control and protect motors used in heating, ventilation, and air conditioning systems.
• Pumps and Compressors: Small pumps, fans, and compressors in a variety of industries might use this motor starter to ensure safe operation and protection.

Specifications (Approximate):

• Motor Size: Typically used for motors up to 1-3 horsepower, depending on voltage.
• Voltage: Often rated for 120V, 240V, or 480V applications (check specific product details for exact voltage range).
• Frame Type: NEMA Size 0 is designed for small motors.
• Overload Protection: Includes thermal overload protection or external overload relay options.
