The unit operates from 220–240 VAC and monitors the line current on the conductor between B and C in a 3 mA to 1 A RMS range, offering two changeover outputs (DPDT) for signaling and interlock functions in control circuits. As part of ABB’s CM-SRS family, this 1SVR730841R1400 variant provides dual signaling paths for monitoring and protection in power‑distribution panels and motor‑control applications where precise current monitoring and clear signaling are required. The CM-SRS.21S designation and 2c\/o outputs indicate its role as a dual-output current monitoring relay for single‑phase mains across typical industrial voltages. \u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656832483630,"sku":null,"price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_59b318bb-9db3-4b1b-aaa3-3f24cc6ecc6a.jpg?v=1769463656","url":"https:\/\/plgautomation.com\/products\/abb-1svr730841r1400-cm-srs-protection-relay-21s-sd","provider":"PLG Automation ","version":"1.0","type":"link"}
