ABB 1SVR750660R0200 Industrial Safety Relay Module

ABB 1SVR750660R0200 is a CM-IWN.1S insulation monitoring relay that supervises insulation resistance in IT power systems, designed for installations up to 690 V AC or 1000 V DC. This 2We variant provides two insulation–measurement ranges, 1–100 kΩ and 2–200 kΩ, and it operates from a 24–240 V AC or DC supply, enabling straightforward integration with standard control circuits. As part of ABB’s CM-IWN.1S family within the 1SVR7500x0 series, the device is intended to monitor insulation health in AC/DC IT networks and industrial installations, alerting users to insulation degradation and helping prevent faults from progressing. Typical applications include data centers, hospitals, and general industrial facilities where reliable insulation monitoring supports safe operation and uptime. The 1SVR750660R0200 is commonly described by distributors as an insulation monitoring relay for 2We configurations with 1–100 kΩ and 2–200 kΩ ranges and a 24–240 V supply, reflecting ABB’s positioning of the CM‑IWN.1S line for IT systems that require continuous supervision of insulation integrity.
