Duplex Control Panels
In a duplex control panel, two motors are used to drain or fill the process adding a level of reliability and easier maintenance. Duplex panels can be configured in a two, three or four “float” configuration. With two remote contacts (floats), only one motor runs at any given time (there is no “lag” operation). With three remote contacts, the motors are operated in a lead-lag mode. With four remote contacts, the motors are in lead-lag mode with an alarm output.
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)
Duplex control panels include:
- NEMA 3R Enclosure;
- (2) Circuit breakers (no external handle);
- (2) Magnetic Contactors;
- (2) Adjustable thermal overload protection;
- 120 VAC control power;
- Fused control circuit;
- (2) Hand-Off-Auto selector switches;
- Alternator operation;
- Terminal block for connection to float switches.
Note: We do not include starting capacitors as standard equipment.
