Phoenix REL-MR-120AC/21-21/MS Single Relay

The Phoenix Contact REL-MR-120AC/21-21/MS relay delivers a robust solution with a nominal input voltage of 120 V AC and a wide operational range from 93.6 V AC to 174 V AC. This single relay utilizes a monostable drive mechanism and non-polarized coil, with a typical input current of 7 mA. It integrates two AgNi changeover contacts capable of switching up to 250 V AC/DC and supports limiting continuous currents up to 8 A and inrush currents of 16 A. With a mechanical service life of 5 million cycles, it is built to withstand long operational cycles in demanding conditions. The relay also provides interrupting capacity up to 2000 VA at 250 V AC for ohmic loads, while the minimum switching current and voltage are set at 10 mA and 12 V respectively. It comes with a plug/solder connection design for simplified panel integration and a 29 mm height that fits compact installations. Operating temperatures range from -40 °C to +70 °C, ensuring reliability in harsh environments. For precise timing, its release time varies between 2 to 8 ms depending on phase relation. This model complies with EN 61810-1 standards and is optimized for control, safety, and motor-starting circuits. For more relay options, view our Phoenix Relay collection.
