Dimensions and mounting holes (mm)
Mounting plates for brake resistor combinations BAS.
Detailed dimensions for specific versions available upon request.
Short-circuit-proof, „intrinsically safe“ resistor for operation with drive controllers (brake transistors), consisting of a combination of individual resistor modules of the 500/600/1000 series, mechanically connected with screw terminals.
These resistor combinations are outstanding in their compact design by virtue of their versatile base plates. Version with IP20 protection class available.
