It runs on a 24 V AC/DC control supply and switches two independent SPDT (2 c/o) contact sets, each rated for the relay's full load curve. Screw terminals simplify panel wiring — strip 8 mm, torque to the terminal spec, and the spring-cage equivalent is not offered on this variant. The 2 c/o (SPDT) output means each of the two contact sets can be wired normally-open or normally-closed independently — useful for breaking both poles of a DC circuit or for dual-signal feedback to a PLC and a separate alarm annunciator. The 24 V AC/DC control supply is a common bus voltage in European-sourced panels; verify your control transformer or PSU delivers 24 V nominal within the relay's operating range (typically 0.8 to 1.1 × Un).","metaTitle":"ABB 1SVR450099R1000 CM-KRN Contact Protection Relay, 24 V AC","metaDescription":"ABB CM-KRN contact protection relay, 24 V AC/DC, 2 c/o SPDT contacts, screw terminals.
