Product Description:
The RZW02.1-037-060 Braking Resistor provides reliable operation across various industrial sectors requiring rapid stopping or deceleration of motor driven systems. Its compatibility with high power frequency converters ensures seamless integration with automation drives.
The RZW02.1-037-060 braking resistor by Bosch Rexroth Indramat has dimensions of 795 mm (W) × 490 mm (D) × 710 mm (H) and a total mass of 80 kg. It is designed for secure fixed installation in enclosed environments and requires a rigid mounting surface to support its static load. The enclosure must allow for adequate thermal dissipation to maintain safe operating temperatures. The braking resistor features an IP20 protection rating. This rating provides protection against solid objects. It is constructed using high thermal conductivity materials and an optimized finned design to maximize heat dissipation. This thermal management reduces the risk of thermal overload. The resistor is engineered to handle high pulse load conditions and regenerative braking energy to ensure stable performance during frequent or intensive deceleration cycles. The braking resistors are configured in one of two layouts: either within a single enclosure divided into two electrically isolated groups or distributed across two separate enclosures if two resistors are specified for a single position. In both configurations, each resistor group is independently connected to the converter via dedicated electrical lines that ensures separate current paths and thermal management.
The RZW02.1-037-060 braking resistor has a nominal resistance value of 7.2 Ω ± 5 % that is suitable for dissipating regenerative energy in dynamic braking applications. The RZW series braking resistor is rated for a peak power dissipation capacity of 33 kW for short duration braking cycles with proper heat sinking and ambient temperature control.
Frequently Asked Questions about RZW02.1-037-060:
