Product Overview
The Siemens 3RR2242-1FW30 is a Sirius series, digitally adjustable three-phase current monitoring relay designed for direct mounting on 3RT2 S0 contactors. It monitors apparent or active current from 4 to 40 A at frequencies between 20 and 400 Hz. With supply voltage ranging from 24 to 240 V AC/DC, it provides one change-over contact and one semiconductor (static) output for alarm and warning functions. Typical applications include motor protection, phase failure detection, and overload monitoring in industrial automation control systems using contactor assemblies.
