Yes. Explanation: The phase sequence control is already activated with contact of the plug with the socket, by which the opportunity is given to correct the rotary field before the engine is switched on with the help of the phase inverter in...
No, the NOLTA-control-unit can be used universal.Instead of a float-switch any switch with NC (normal closed)-characteristics could be used.In the case of variations with extra low voltage-surveillance (5V = galvanically disconnected from the ...
Yes. Explanation: The warming of the winding does not only depend on the current consumption, this could happen for instance in the case of reduced refrigeration (dry run of pumps, etc.).
By the use of extra low voltage the result is a essential lead in case of security, and is therefore recommended by the employees insurance.In the case of damage on the cable to the float-switch no dangerous contact voltage occurs.By the...
There is no neutral conductor for the operation with NOLTA-thermal contact monitor necessary.Essentially lower current- and voltage additional charge of the teperature-monitor-contacts in the winding area.
If you have thermal protection the engine is protected against lasting overcurrent in the winding area according to its rated current. If you have thermal-magnetic protection a short-circuit protection according to the rated current of ...
