Monitoring relay, mountable on contactor 3RT2, size S00 standard, digitally adjustable. Apparent/real current monitoring 1.6-16 A, 20-400 Hz, 3-phase supply 24-240 V AC/DC. 1 changeover contact, 1 semiconductor output for alarm and warning. Monitoring for current over- and under-run, phase failure, wire break, phase sequence, earth fault, and blocking current. Warning and alarm thresholds with or without fault memory. Start-up delay 0-99 s, disturbance peak suppression 0-30 s, pause after fault 0-300 min. Spring-loaded technology. SIRIUS 3RR2 monitoring relay for plugging onto SIRIUS 3RT2 contactors or for standalone use for multi-phase current monitoring of the entire system or the driven process. Reliable monitoring for cable break, phase failure, phase sequence, earth fault, motor blockage, and more enhances system availability. Actual value displays, status messages, and clear fault messages enable quick and reliable diagnostics. Control connection via IO-Link is also possible. You save costs as only one device is required to monitor a motor across the entire torque curve, and no separate current transformers are needed. The direct mounting on contactors 3RT2 eliminates additional wiring effort in the main circuit. Additionally, benefit from wide-range power supplies for global use. Available are analog adjustable, 2-phase variants and digitally adjustable, 3-phase variants (with and without IO-Link), each in three sizes with different current measurement ranges, two different supply voltages, and two connection types. Suitable carriers are available for standalone use of the 3RR2 monitoring relays. SIRIUS relays - a program for all cases.
