Product Description:
The RZW02.1-007-040 Braking Resistor is made by Bosch and is used to dissipate extra heat to the surroundings. This product supports energy dissipation during braking in motion applications. This Indramat RZW braking resistor offers reliable operation in automation setups.
The RZW02.1-007-040 braking resistor supports frequency converter power up to 7.5 kW. The unit is rated for 40% switch-on duration for braking cycles and provides safe and repeated braking performance. The thermal time constant value of the RZW resistor is 150 seconds. The operating factor is defined as 25% switch-on duration. The minimum connectable resistance value is 30 Ohm which stabilizes energy control during braking. The peak power handling capacity is rated at 3.5 kW which supports short-cycle energy loads. The required conductor cross-sectional area is 2.5 mm². The cross-section requirement offers secure electrical connectivity. The housing is constructed using galvanized steel for durability. The housing design includes external ventilation support. The 150-second time constant allows balanced energy absorption. The galvanized housing protects against mechanical and thermal stress. The unit handles repetitive braking events without overheating. It has an IP 23 protection which protects internal components from particles and sprays. The steel housing supports ventilation through external airflow systems. It fits in control cabinet designs, because of its compact build.
The RZW02.1-007-040 braking resistor is perfect for medium-duty energy control. This resistor offers stable operation during frequent motor deceleration. This Indramat RZW braking resistor is made for controlled braking and its design supports safe thermal dissipation across a range of applications. The small design makes the integration into automation panels easy. The design helps reduce braking load stress on the drive system. The innovative design and durable construction allow long-term usage in harsh environments.
