Simplex Control Panels

A simplex level control panel is the right choice for non-critical level control where a single pump or motor is utilized to drain or fill a process. In a “two float” configuration, the motor starts when one remote contact, a float switch for example, closes and the motor stops when the other remote contact opens. A “three float” configuration provides the same operating sequence, but a third remote contact is used as a high level or a low level alarm.

New Utility Transformers allow higher available Fault Currents. When advised, we can provide controls with proper interrupting ratings. Short Circuits may cause welding, which is not considered a failure of the Contactor. (see UL508, Para 53)

Simplex control panels include:

  • NEMA 3R Enclosure;
  • Main Circuit breaker (no external handle);
  • Magnetic Contactor;
  • Adjustable thermal overload relay;
  • Reset pushbutton;
  • 120 VAC control power;
  • Fused control circuit;
  • Hand-Off-Auto selector switch;
  • Terminal block for connection to float switches.

Note: We do not include starting capacitors as standard equipment.
