Steel grid resistors

Steel grid resistors consist of individual steel grid elements from the S series, which are used to construct the resistor blocks of the FE or FEY series. The resistor blocks are then assembled into steel grid resistor units, which are available with various degrees of protection and mounting options.

Features

Very favourable price-performance ratio with high quality
Choice of over 60 different individual elements from 0.0022 to 6.8 Ω
High current carrying capacity up to 400 A per steel grid; can be further increased by parallel connection
Lower dependence of the resistance value on temperature than with cast resistors due to lower temperature coefficient
Overload-proof for short-term loads thanks to high heat capacity
Very robust design and therefore insensitive to vibrations
Housing made of strip-galvanised sheet steel
Air and creepage distances designed for earthed three-phase networks up to 3 x 500 V and derived voltages. Test voltage 2.5 kV AC.

Options

Temperature switch for temperature monitoring
Thermal overcurrent relay for high operational safety (FGFT series)
UL recognition for the American and Canadian markets (E212934) possible for all marked series
Housings for selected series available in stainless steel 1.4301 or 1.4404
