Motor Controls

Definite Purpose Contactors

Definite purpose contactors are designed for application-specific use, such as HVAC or compressors, providing reliable load control that can handle diverse switching needs. These compact contactors are available in up to 60A capacities, in 1- or 3-phase configurations, and with coil voltages from 120 to 480 VAC.

Motor Disconnects & Controllers

Manual motor controllers and disconnects safely control and disconnect power from motors. UL 508 rated open frame and enclosed devices are available from reliable brands including Bryant, Merz, and Socomec.

Motor Control Relays

Motor control relays perform protective functions for motors and components to ensure proper and efficient operation. Phase monitoring relays detect faults in a 3-phase system; alternating relays balance load usage; pump seal failure relays monitor pump shaft seals.

AC Variable Frequency Drives (VFD)

Newest Additions!

AC Motor Soft Starters

Solid state soft starters provide many advantages when used instead of electro-mechanical contactors, including reduced shock and starting stress on motors, resulting in an extended motor lifespan.

• Compact WEG SSW05 and Stellar SR22 series offer a reduced footprint for solid state motor control in ratings up to 85A (depending on series). SR22 starters are available for 1- or 3-phase motors.
• Basic WEG SSW07 and Stellar SR35 series provide dependable performance on motor starts and stops, in ratings up to 412A (depending on series) and a selection of trip classes
• Full-featured Stellar SR55 series starters are fully digital, and use thyristors in all three motor phases for controlled reduced voltage motor starting and stopping; available in ratings up to 477A, and AC or DC control voltages

DC Drives

IronHorse DC drives can accommodate from 1/50hp @ 12VDC out (with 12VDC in) up to 3hp @ 180VDC out (with 240VAC in). DC motors and drives can provide several advantages:

• Inexpensive
• Low speed performance
• Low speed power
• Simple
  • DC drives typically use potentiometers for configuration
  • No parameters or programming needed (for most models)
  • Feature-rich (some models include communications)
  • Default programming handles most applications
