Steel grid resistors
In drive engineering, GINO steel grid resistors are suited for application in combination with motor starters or contactor controls for the starting and control of alternating current slip ring rotors or direct current motors. They are equally suited as slip, series or load resistors. These resistors exhibit a particularly high vibration resistance and low weight. Due to the large surface of the resistor elements in relation to their mass, they are preferably used in continuous operation or intermittent operation with high relative duty factors.
As the authorized supplier for Siemens steel grid resistors, system 3PS3, GINO manufactures and supplies spare parts and units for the superseded system Siemens 3PS1 as well as its own GINO/ESE system.
The GINO resistors comply with the specifications of the applicable VDE standards VDE 0100 and VDE 0660. They conform to the EEC Low Voltage Directive of 19 February 1973.
Pursuant to DIN EN60529:2014-09; VDE0470-1:2014-09, IEC 60529:1989 + A1:1999 + A2:2013, EN 60529:1991 + A1:2000 + A2:2013 IP00, IP10, IP13, IP20, IP23 are available depending on the respective system.
The rated insulation voltage is 1000V AC/1200V DC at a pollution degree of 3 pursuant to VDE 0110. Test voltage 3.5 kV - 50 Hz - 1 min
The resistance values indicated in the tables of our technical catalog are nominal values. A nominal value is approx. 10% higher than the cold resistance value. The manufacturing tolerance is ±10%. This means that the ohm values of the resistors in cold condition are Rcold = 0.9RNom±10%. The hot value is of around 1.15 x nominal value ±10%.
Steel grid resistors are suited for climates A, F H, M and T, climatic class "General" pursuant to DIN EN 60721-2-1:2015-10; VDE 0468-721-2-1:2015-10, IEC 60721-2-1:2013, EN60721-2-1:2014 and climatic classes J3, A and F2 pursuant to Siemens standard SN29070T1 and thus suited for indoor and outdoor installation with varying conditions of condensation, without protection against weathering at low pollution impact. The admissible ambient temperature range is -25 to +45°C and the units can be operated at elevations of up to 1000 m above the sea level. At higher temperatures or higher altitudes, the load carrying capacity and/or the rated voltage must be reduced as a function of the operating mode KB/AB/DB or the installation altitude.
