Brake Resistor Combinations
B3H...V
Short-circuit-proof, „intrinsically safe“ resistor for operation with drive controllers (brake transistors), consisting of combinations of individual resistor modules of the 600/1000 series.
These combinations of resistors are distinguished by their compact design and their additional touch protection. They are suitable for both, wall mounting and mounting on the control cabinets top. Standard version with IP65* protection class.
