RZW Braking Resistors
The RZW02.1-022-040 from Bosch Rexroth Indramat’s RZW Braking Resistors series is a rugged wall-mounted braking resistor designed for industrial automation, featuring a 22 kW power class and a resistance of 2.5 Ω for efficient energy dissipation. Its galvanized steel housing rated IP23 ensures durability and protection, while axial ventilator with wind vane relay cooling combined with natural convection maintains optimal thermal management. With a thermal time constant of 100 s, a switch-on cycle basis of 120 s and a max on time of 48 s at 40% duty, it supports reliable deceleration. Heavy-duty power & signal connectors simplify installation and enhance vibration resistance.
