Why Choose the ABB CM-ENE MIN Liquid Level Relay?
The ABB CM-ENE MIN 1SVR550855R9500 is a compact and reliable liquid level monitoring relay designed for minimum-level monitoring and dry-running protection in industrial control applications. As part of the ABB CM-ENE measuring and monitoring relay series, it monitors the conductivity of liquids through electrodes and provides dependable control for pumps, tanks and process systems.
Designed specifically for draining monitoring and dry-running protection, the CM-ENE MIN detects the minimum liquid level and provides a relay output for integration with control circuits. Its conductive measuring principle makes it suitable for electrically conductive liquids, while the compact housing helps minimise panel space in industrial control cabinets.
This version operates from a 24 V AC rated control supply and provides a 0–100 kΩ measuring range. It features one normally open output contact, a two-electrode sensor circuit including the ground reference, screw terminals and a slim 22.5 mm housing width.

Reliable Minimum Liquid Level Monitoring
Conductive liquid level monitoring relays detect the electrical resistance between electrodes positioned in a tank or vessel. The ABB CM-ENE MIN uses this principle to determine when a conductive liquid reaches or falls below the monitored minimum level, allowing the relay output to interact with pumps, contactors, alarms or other control equipment.
The minimum-level monitoring function is particularly useful for dry-running protection. By detecting insufficient liquid before continued pump operation causes problems, the CM-ENE MIN can form an important part of reliable pumping and process-control systems.
Typical Applications
- Pump dry-running protection.
- Minimum liquid level monitoring in tanks and vessels.
- Draining control systems.
- Industrial water and process systems.
- Pumping stations and machine systems.
- Industrial control and automation panels.
