Application Notes
Monitoring relay MCR-32 serves to monitor current level in single phase AC circuits. Due to its fl uent adjustment of release current, it is predestined for applications with necessity of current flow indication, and can be used as precedence relay. Output relay is off in normal state. In case the set current level is exceeded, it switches. Multivoltage supply is an advantage.
