2-module adjustable differential relay designed for mounting on DIN profile. Its main function is to detect leakage currents in three-phase power systems, offering adjustable protection by threaded connection.
Technical characteristics
- Power voltage AC: 195.5...253 V to 50/60 Hz.
- Rated operating frequency: 47...63 Hz.
- Differential intensity response range: 30...30000 mA.
- Adjustable activation delay: 5 s.
- Includes 1 investment contact and 0 NA/NC contacts.
- Differential intensity indication and error recording.
- Dimensions: 35 mm wide, 89 mm high and 65.6 mm deep.
This device allows you to set the trigger threshold and delay time to suit the specific needs of the three-phase electrical installation. The presence of an investment contact facilitates integration into external control or signalling schemes.
