Reliable Protection Against Overtemperature – EMT6 Thermistor Overload Relays

EMT6 thermistor overload relays protect machines against overtemperature caused by heavy starting duties, braking, undervoltage, overvoltage, and high switching frequencies. When using these relays, a thermistor is used to monitor the temperature directly on the motor winding and, in the event of overtemperature, the corresponding signal is relayed to the EMT6 unit. Once the unit receives the signal, it trips, and the fault signal can be reliably detected in the corresponding control panel.

EMT6 units are also 

used to monitor the temperature of bearings, gears, oils, and coolants. Moreover, there are a variety of device models available with additional functionalities, including protection against the effects of voltage loss, short-circuit monitoring, and the ability to switch between automatic and manual switching-off.

All devices are devices for world markets to IEC/EN 60947 with UL/CSA approval.

Easily perform function tests 

The relay's functionality needs to be tested on a regular basis during commissioning and maintenance. To make this as easy as possible, all EMT6 models feature an integrated Test button that can be used to simulate an error condition.
