overload relay / temperature / 1NC / three-phase

The EMT 6-DBK is used for automatic or manual operation functions, short circuit detection in the sensor circuit and zero-voltage safety to ensure reliable fault signalling during supply voltage failure. The EMT 6-DKB can suitably used for every thermistor application for simplified selection, engineering and stock-keeping. Optimal safety is ensured through the potential isolation between the sensor circuit and the control supply voltage. The unit comes in three versions of EMT 6, EMT 6-DB and EMT 6-DBK.

EMT 6-DBK guarantees maximum protection of machines against over-temperatures during severe starting duty, braking duty, undervotage and overvoltage, and high operating frequency. The monitoring winding enables direct temperature monitoring. EMT 6 is signalled during over-temperature. The unit is used in monitoring of temperatures in bearing, gearboxes, oils and coolants
