Protective Relays and Monitoring Relays from RS Components, Ltd.


262031 -- View Larger Image

Relays HWTM and HWTM2 check the availability of the 3 phase network and the temperature of the motors using integrated PTC probes. The phase and temperature control functions are independent of one another.
Control of 3 phase networks: phase sequence, phase failure. Multi-voltage. True RMS measurement. Motor temperature control via PTC probes. With line break or probe short-circuit detection. Version with fault latching function and reset / test. LED status indication
