RZW03.1-037-040
RZW Braking Resistors
The Bosch Rexroth Indramat RZW03.1-037-040 braking resistor from the RZW Braking Resistors series provides reliable energy dissipation for industrial automation. It delivers a 37 kW power rating and supports a 40% switch duty cycle with T_onmax = 48 seconds and T_off = 72 seconds, achieving a peak to continuous power ratio of 2.2. Its thermal time constant of 150 s ensures stable temperature response, while the galvanized steel plate housing offers corrosion resistance. With a protection class of IP 23 and approximately 15 kW continuous braking power, this Type RZW resistor meets demanding operational requirements.
