- Contactors, also known as across-the-line starters, are the most basic form of motor control. Contactors provide full power and torque to the motor immediately after the start command. Reversing and speed control is not available, but this control type is suitable for common motor applications.
- Softstarters reduce the strain on your motor during startup. Reversing and speed control is not available with a softstarter.
- Variable speed drives
- Like softstarters, drives reduce the strain on your motor during startup. They also have the added benefits of motor speed control and increased efficiency.
- NEMA Type 1
- Indoor - Provides a degree of protection to personnel against access to hazardous parts and to provide a degree of protection of the equipment inside the enclosure against falling dirt.
- NEMA Type 3R
- Indoor/Outdoor - Provides a degree of protection to personnel against access to hazardous parts; to protect the equipment from falling dirt, rain, sleet, snow, and the formation of ice.
- NEMA Type 4X
- Indoor/Outdoor - Constructed from stainless steel. Provides a degree of protection to personnel against access to hazardous parts; to protect the equipment from falling dirt, water (rain, sleet, snow, splashing water, and hose directed water), corrosion, and the formation of ice.
The ACS580 is plug-in ready to control your pumps, fans, compressors, conveyors, mixers and many other variable and constant torque applications. To select the right drive, you must first determine the correct overload rating for your drive application.
- Light duty use
- 10% overload for 1 minute every 5 minutes.
- Heavy-duty use
- 50% overload for 1 minute every 5 minutes.
**If you are unsure whether you need a light duty or heavy duty drive, please consult your local ABB representative.**
*Note: the load capacity of the drive decreases for certain applications. For example,
- Drive frames R0…R3 at an ambient temperature > 50°C must be derated.
- Drive frames R5…R9 at an ambient temperature > 40°C must be derated.
- Drives operated at switching frequencies > 1 kHz must derated.
- Drives operating at altitudes > 1000m must be derated.
To ensure that your drive is rated correctly, please consult your local ABB representative.
Controller Disconnect – a separate disconnect switch is required for each controller and must be within sight AND no more than 50ft from the controller.
Motor Disconnect – a second switch is required to be installed next to the motor unless the controller disconnect is within sight AND no more than 50ft from the motor.
Combination Starter – includes a fused disconnect switch, contactor, and overloads in a single NEMA style enclosure. This provides short-circuit and ground fault protection for the motor.
Non-combination Starter – includes just the contactor and overloads in a NEMA style enclosure. If you choose a non-combination starter a separate disconnect switch might be required at the motor per the NEC.
- Normal starts (class 10)
- For most general use applications such as band saws, bow thrusters, centrifugal pumps, circular saw, conveyer belt short, cutter, escalator, high pressure pumps, hydraulic pumps, elevators, piston and scroll compressors.
- Heavy duty starts (class 30)
- For most heavy duty and industrial applications, such as axial fans, long conveyer belts, crushers, centrifugal fans, grinders, and mixers.
*If you require an inside-delta softstarter configuration, consult hardware manual.*
**If you are unsure whether you need class 10 or class 30 softstarters, please consult your local ABB representative.**
