FAQs
ABB 1SVR730850R2100 is designed for DIN rail mounting using TH35-15 or TH35-7.5 profiles. It supports screw-terminal connections for flexible wiring and includes front-face potentiometers to adjust sensitivity without opening the housing. This combination simplifies panel layouts and reduces installation time while maintaining secure, vibration-resistant terminations in busy electrical cabinets. Suitable for global projects, it aligns with IP50 housing and 3-electrode configurations.
CM-ENS.13S uses an open-circuit sensing principle and a 1 c/o SPDT output rated 250 V at 4 A, enabling direct pump control and reliable dry-run protection. The adjustable 5–100 kΩ range and three-electrode configuration let you tailor sensitivity for various conductive fluids, while screw terminals and double-chamber terminals deliver secure wiring in industrial cabinets.
This device carries CE and UKCA markings for Europe, UL/CSA for North America, CCC for China, and DNV GL in its certification suite, along with RoHS and REACH declarations. These certifications support regulatory compliance, safety certification, and supply-chain acceptance, reducing time-to-market for global deployments and ensuring performance under UL 508 and IEC 61000-series environmental standards. They also align with CCC and SCIP traceability requirements for responsible sourcing.
The CM-ENS.13S offers screw-terminal wiring, front-face sensitivity adjustment, and a sealable cover to guard against tampering, all supporting quick commissioning and easy ongoing maintenance. DIN-rail mounting options and supplied electrodes simplify installation in compact panels, while the open-circuit sensing method minimizes fouling-related drift. Accessories like additional electrodes extend life in harsh environments.
Operating from 110–130 V AC or 220–240 V AC, the CM-ENS.13S supports your regional mains without rewiring, with a 50/60 Hz supply and SPDT output rated up to 4 A. It handles ambient temperatures from -25 to +60 C and up to 2000 m altitude. Ensure IP50 housing, IP20 terminals, and appropriate fusing per system design.
