Grundfos LC 241 2 x 52-65 SST 415v MI Indoor Dual Pump Wastewater Pump Controller for Drainage

Drainage systems in indoor commercial settings benefit from this controller's dual pump automation capabilities. It coordinates pump operation by accepting signals from analogue level transmitters or float switches, ensuring pits and collection sumps remain within operational limits. The system supports automatic pump sequencing and alternation, providing consistent service duty for commercial installations.

Electrical specifications for the Grundfos LC 241 2 x 52-65 SST 3X230/400 MI OPT support 415v three-phase pumps with a 52-65 A current rating per motor. Soft starter technology enables controlled acceleration, reducing mechanical stress on pump components during start-up. The system operates on 50/60 Hz mains frequency with individual motor current monitoring supporting overload protection.

Bluetooth commissioning via the Grundfos GO app enables wireless configuration of start and stop levels without cabinet access. Configurable inputs support analogue level transmitters, float switches and compatible level sensors for customized site requirements. Integrated dry-running protection and BMS connectivity support unattended operation while maintaining alarm logging for system events.

A painted metal cabinet with IP54 enclosure protects internal components in wall-mounted indoor installations. This RCM compliant controller operates in ambient temperatures from -5°C to +40°C and includes a front control panel for status visibility. Manual reset capability and immediate access to system warning logs are provided through the front-mounted interface.
