Terminal covers for protection against inadvertent contactwith exposed bar connections (DIN VDE 0106 Part100/EN 50274)
The covers are suitable for all reactors and filters with 1-holeflat connectors. Assignment of the covers to the reactors andfilters can take via the connection hole diameter.
If no other information is provided in the technicalspecifications, touch protection for the backs of hands againstunintentional contact with live components can be created accordingto BGV A2 by using the covers.
Reactors for AC operating mechanisms
Three-phase mains reactors for frequency converters are used inline-side infeeds. They are connected such that alternatingcurrents with line frequency as the fundamental wave frequency flowthrough them.
The reactors limit the circuit feedback which can arise in the formof harmonics. In addition they reduce the alternating currents,with frequencies caused by switching of the input rectifier, in theDC link capacitors.
Two reactor series are available in the version Standard (CatalogLV 60):西门子一级代理商|PLC中国代理商
Reactors with a related voltage drop uD of~ 2 % for operation with converters without powerrecovery.
Reactors with a related voltage drop uD of~ 4 % for operation with converters together withautotransformers with power recovery and for use in networks whichhave a uk networkof < 1 %.

Iron output reactors for AC operating mechanisms
Output reactors are used on the load side of frequency convertersand motor currents flow through them.
Output reactors compensate capacitive charge-reversal currents withlong cables and, in the case of long motor cables, limit the dv/dtat the motor terminals. This enables the use of longer motor supplycables:
200 m shielded motor cable
300 m unshielded motor cable
Use of iron-core output reactors:西门子一级代理商|PLC中国代理商
Operating mechanisms with standard and trans-standardasynchronous motors and a rated motor frequency (field weakeningfrequency) of up to 87 Hz and a maximum frequency of 200 Hz.
Operating mechanisms with reluctance or permanently excitedsynchronous motors with a maximum frequency of 120Hz.西门子一级代理商|PLC中国代理商
Note on theversions Standard(Catalog LV 60):
The following generic parameters apply, which must not beexceeded:
Maximum motor cable length 200 m, shielded cable
Maximum motor cable length 300 m, unshielded cable
Maximum motor cable cross-sections for performance class:
up to 2.2 kW/1.5 mm²
> 2.2 kW ≤ 7.5 kW/2.5 mm²
> 7.5 kW ≤ 11 kW/4 mm²
> 11 kW ≤ 22 kW/10 mm²
> 22 kW ≤ 30 kW/16 mm²
> 30 kW ≤ 37 kW/25 mm²
> 37 kW ≤ 50 kW/35 mm²
> 50 kW ≤ 75 kW/70 mm²
