Product Overview
The Siemens 3RR2242-2FA30 is a member of the SIRIUS 3RR22 series of digitally adjustable three-phase current monitoring relays. It is designed to monitor active or apparent current within a defined range and provide both a change-over contact output and a semiconductor warning output. Used for protective and alerting functions, it integrates into motor control and contactor systems (e.g., with 3RT2 contactors) and finds applications in phase-sequence protection, residual current detection and threshold-based alarm systems.
Best Suited For
- Monitoring three-phase motor current using 3RT2 contactors
- Detecting phase sequence and phase loss conditions
- Setting separate warning and alarm thresholds
- Providing both relay and semiconductor alarm outputs
- Delay-based fault recovery and reclosing via timer settings
