The QMD and QTD are sewage control panels with a thermo-plastic IP55 enclosure for use with float switches to control two single phase (D.O.L. 110-230V) or two three phase (D.O.L.400V) pumps. They feature motor protection, with a wide current range, that can be manually adjusted and set to a motor’s full load current, avoiding the usual, awkward overload changes. One panel type is therefore suitable for a broad range of motor sizes. They also include low voltage transformer, motor fuses, hand/off/auto switch, run and trip indicator lamps, auto-changeover relay, built in alarm output and duty/standby or duty/assist option. Capacitors, for single phase use, are not supplied. The panels can be used with 3 or 4 float switches, differential or direct. Optional extras available are audible alarms, audible/visual alarms, remote control and timed control.
