Motor Control Products Available from Power Quality and Drives LLC
Copyright © 2007 Francis J. Martino

A variety of standard controls are available that are not offered in our on-line store.
Just e-mail your specifications to receive a quotation.

Standard controls include:

Relays with NO and/or NC contacts 4, 6, or 8 poles
      Connection types available: Screw clamp, Fast-on, Cage Clamp, or Solder pin.
      All relays have provision for Screw or DIN Rail mounting.

AC Definite Purpose Contactors
      Definite Purpose Contactors were originally designed for the refrigeration industry. The
      refrigeration industry went to the control manufacturers and asked for contactors that
      would be rated for motor starting that would be lower in cost than the more rugged NEMA
      rated contactors that were used for industrial applications. The definite purpose
      contactors were developed with the duty cycle capability of the refrigeration industry which
      has much fewer starts and stops on a daily basis than industrial machinery. If a definite
      purpose contactor is applied to industrial machinery then it will not be covered by
      warranty unless the manufacturer specifically approves of the application.

Enclosed Starters, Type 1 Enclosure, w/Start and Stop Pushbuttons
      Up to NEMA size 4 is listed in our store. NEMA size 5, 6 and 7 are available upon request.

Enclosed Starters, NEMA 4/12 Enclosure, w/Start and Stop Pushbuttons
      Up to NEMA size 5 is listed in our store. NEMA size 6 and 7 are available upon request.

      Options available for starters: Disconnects, Type 1, 3R and 4 Enclosures.

Reversing contactors, starters
      For those emergency situations when a reversing contactor or starter is needed immediately,
      the components may be shipped for you to assemble and wire: two 3-pole contactors, one
      overload relay, two auxiliary interlocks (1NO, 1 NC), one mechanical interlock, one
      base plate. Specify motor volts, full load amps and coil voltage.

Two Speed, Two Winding Motor Starters
      For those emergency situations when a two speed, two winding motor starter is needed
      immediately, the components may be shipped for you to assemble and wire: two 3-pole
      contactors, two overload relays, two auxiliary interlocks (1NO, 1 NC), one mechanical
      interlock, one base plate. Specify motor volts, full load amps and coil voltage.
