Product Description:
Bosch Rexroth is a global manufacturer of drive and control technologies. It delivers automation components for industrial motion control systems. The company’s products ensure efficient and reliable machine performance across a wide range of industries.
The RZW02.1-003-060 Braking Resistor is a compact and robust device. It features dimensions of 389 mm width, 75 mm depth and 87 mm height. The minimum connectable resistance value is 30 ohms. The unit requires a minimum off time of 48 seconds for cooling. This ensures proper heat dissipation between operating cycles. It has a duty cycle of 60 % which specifies the resistor is active during 60 % of each operating period. The resistor weighs 1.2 kg that makes it lightweight for installation. It is a Type A resistor and is built for industrial braking applications. The design supports installation parallel to an assembly surface. This configuration simplifies mounting and improves thermal stability during operation. This resistor uses a cemented wire wound pipe fixed configuration. The wire is encased and protected by lateral components and a perforated metal cover. This design ensures safe operation and heat resistance. The unit includes two electrical connections each wired to porcelain terminals. These terminals are housed in an attached terminal box for added protection. The terminal box includes PG screws for secure and reliable wiring. The enclosure of the braking resistor also supports structured cable routing.
The RZW02.1-003-060 braking resistor from the RZW series can be protected against thermal overload by utilizing the integrated monitoring function within the RD 500 firmware which continuously tracks the resistor's duty cycle, power dissipation and temperature thresholds to trigger protective actions when predefined limits are exceeded.
