With a rated control supply voltage of 110-130 V AC and a single normally open output, the CM-ENE MIN fits neatly into standard pump control circuits, reducing design complexity and parts count. This compatibility translates into faster commissioning and lower errors during wiring in OEM and retrofit projects. The 0-100 kΩ measuring range provides flexible sensing for a wide variety of liquids, enabling reliable dry-run protection across water, wastewater, and process fluids. The fixed sensitivity ensures predictable triggering and consistent pump protection without adjustments in the field. Two electrodes deliver accurate level detection while the screw-terminal connection supports robust terminations in industrial enclosures. IP50 housing protects the electronics from dust ingress, while compliance with CAN/CSA, IEC/EN standards ensures safe operation in demanding environments. DIN-rail mounting options TH35-15 or TH35-7.5 and a compact footprint streamline installation inside existing control cabinets. These features translate into safer operation and measurable cost savings across water treatment, irrigation, and process cooling applications.

FAQs
The CM-ENE MIN is designed for DIN-rail mounting TH35-15 or TH35-7.5. Install the relay by snapping it onto the rail in the control cabinet, then terminate the two electrode cables to your liquid level probes using the screw terminals. Ensure the enclosure is closed and tighten the terminal screws to the recommended torque for reliable operation.
The unit operates from 110 to 130 V AC with a single normally open (NO) output. In AC-12 terms, it supports up to 4 A at 230 V, and up to 3 A for AC-15, making it suitable for direct control of pumps and other actuator loads in typical industrial panels.
Yes. It is specifically designed for dry-running protection with two electrodes and a 0–100 kΩ measuring range. Its 1 NO contact provides a straightforward control signal to stop or start pumps, helping prevent seal damage and motor burnout in pumping systems.
The CM-ENE MIN supports CE and UL 508 certifications, with UKCA readiness. It also carries IP50 housing protection for indoor use and is compatible with CAN/CSA C22.2 No.14 and IEC/EN standards, ensuring safe operation within industrial control environments.
By preventing dry-running, the relay reduces unplanned downtime and extends pump life, lowering maintenance costs. Its screw terminals and DIN-rail mounting simplify installation and future retrofits, delivering faster commissioning and a lower total cost of ownership in municipal, industrial, and process cooling applications.
