Sewage Pumps for Building ServicesElectrical accessories Wilo-DrainProduct descriptionsSwitchgear Wilo-DrainControl PL 21 2Switchgear Wilo-DrainControl PL 2 WSSwitchgear for regulating the levels of 2 submersible motor pumps. Level measurement can becarried out with either the bubbling-through or the dynamic pressure procedure, via an electroniclevel sensor 0-2.5 mWs (4-20 mA) or float switch (WA65, WA 95 or MS1).• LCD display, multi-language switching• LED for alarm, operation/follow-up time, manual/automatic operation• Potential-free contact for collective fault signal and high water alarm, pump malfunction 1,pump malfunction 2• Forced switch-on of the pump• Pump switch-off with follow-up time• Automatic fault-actuated switchover• Integrated buzzer• Operating hours counter, pump startsTechnical data:Operating voltage: 1~230 V, 3~400 VFrequency: 50/60 HzProtection class: IP 65 (within buildings/switch cabinets)Dimensions (W x H x D): 320 x 300 x 120 mmNote: Switchgears are not protected against explosions and may not be utilised except outsideof potentially explosive areas. A level sensor in the Ex area (with breakdown barrier!) or a floatswitch (in the Ex area with Ex-uncoupling relay) is to be provided for pump control.Submersible Motor Pumpswith MaceratorSubmersible Motor Pumpswithout Macerator1 2Switchgear for regulating the levels of 2 submersible motor pumps.Level measurement can be carried out with either the bubbling-through or the dynamic pressureprocedure, via an electronic level sensor 0-1 mWs (4-20 mA) or float switch (WA65,WA 95 or MS 1).• LCD display, multi-language switching• LED for alarm, operation/follow-up time, manual/automatic operation• Potential-free contact for collective fault signal and high water alarm, pump malfunction 1,pump malfunction 2• Forced switch-on of the pump• Pump switch-off with follow-up time• Automatic fault-actuated switchover• Integrated buzzer• Operating hours counter, pump starts• Lockable main switch• 3~mains, no neutral conductor requiredElectrical AccessoriesWilo-DrainTechnical data:Operating voltage: 1~230 V, 3~400 VFrequency: 50/60 HzProtection class: IP 65 (within buildings/switch cabinets)Dimensions (W x H x D): 320 x 300 x 120 mmFlag4Note: Switchgears are not protected against explosions and may not be utilised except outsideof potentially explosive areas.
