CM-IWSABB 1SVR730670R0200 CM-IWS.2S Insulation and Earth Fault Monitoring Relay 1 C/O 1-100kΩ 24-240VAC/DC
Description
About the CM-IWS.2S
About the CM-IWS.2S
The ABB CM-IWS.2S insulation and earth fault monitoring relay (SKU: 1SVR730670R0200) continuously monitors the insulation resistance of unearthed AC, DC, and mixed electrical systems, providing a single changeover (1 C/O) output contact when insulation resistance falls below the set threshold. Designed for control panels and industrial automation environments, the CM-IWS.2S supports a wide monitoring range of 1–100 kΩ and operates across a broad supply voltage range of 24–240V AC/DC, making it suitable for diverse global applications.
