ABB 1SVR550851R9500 Liquid Level Relay - CE/UL 508

Rated control supply voltage of 220-240 V AC ensures seamless integration with common mains in industrial facilities, reducing wiring complexity and enabling faster deployment. Business impact: simplified installation and reduced commissioning time for pumping systems in water treatment and process plants. Application: direct connection to main power supplies and pump circuits with screw terminals for secure wiring. Output is a single normally open contact, providing straightforward switching and easy fault isolation; impact: predictable pump control and easier fault tracing during maintenance. Application: single-pump or small-pump banks in municipal or industrial water systems. Measuring range of 0 to 100 kΩ with two electrodes enables resilient level sensing across a variety of liquids, improving protection against dry running and enabling calibrated response. Impact: lower false trips and improved reliability in variable liquid conditions. Application: level sensing in tanks, sumps, and reservoirs where electrode-based monitoring is preferred. The device supports screw terminals, simplifying field wiring and ensuring robust connections in dusty or vibration-prone environments; impact: reduced terminal loosening and maintenance downtime. Application: panel assemblies and enclosures with DIN-rail mounting. With rated operational currents of 4 A AC-12 at 230 V and 3 A AC-15, the relay suits low-to-medium load applications, delivering safe switching without oversizing components. Impact: cost-efficient protection and reliable pump control in water and light-process circuits. Application: pump protection in HVAC and cooling loops. The CM-ENE MIN also provides solid insulation with 4 kV impulse withstand and 250 V insulation between circuits, supporting compliant operation in mixed electrical environments; impact: enhanced safety margins and compliance with electrical standards. Application: use in systems requiring separation between sensing, control, and power circuits. Mounting on TH35 DIN rails (35 x 15 or 35 x 7.5 mm) and screw-terminal connectivity provide flexible installation options, enabling compact layouts in control panels. Impact: maximize enclosure efficiency and simplify retrofits or upgrades in existing installations. Application: retrofit projects or new installations in machine automation zones. Overall, its compatibility with UL/CSA, CE, and RoHS standards ensures readiness for global deployments, reducing supplier risk and accelerating project timelines.
