3RR2 Monitoring Relays

Siemens 3RR2 Monitoring Relays are designed for continuous supervision of motor currents and load conditions in industrial control panels. These relays are mounted directly onto RT2 contactors for compact motor starter assemblies. The 3RR2 monitoring relays detect various faults, including overcurrent, undercurrent, phase failure, cable breaks, current asymmetry, and blocked‑rotor conditions, to prevent machine damage and reduce downtime. These relays are available in three sizes: S00, S0, and S2. The 3RR2 monitoring relays are conceived for monitoring 3-phase systems.
