Brake Resistor Combinations
B3H...H
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. These are only suitable for wall mounting. Standard version with IP65* protection class.
