Product Description:

The RZW02.1-005-025 is part of the Bosch Rexroth Indramat range of augmented braking resistors, designed for dynamic braking tasks that require robust power. This model efficiently dissipates braking energy in applications with large inertia masses or extended braking processes, ensuring smooth deceleration. It is ideal for use in heavy-duty industrial environments such as cranes, lifts and conveyor systems. The resistor’s 5.5 kW output makes it highly efficient for dynamic braking tasks, ensuring smooth deceleration even in systems with high inertia.

The RZW02.1-005-025 has a minimum connectable resistance value of 30 Ω, ensuring that the braking resistor is compatible with a wide range of braking applications. This resistance value allows for optimal energy dissipation and effective braking performance in systems requiring substantial braking power. The resistor comes with a conductor cross-sectional area of 2.5 mm², which is critical for managing high current levels during dynamic braking tasks. The 2.5 mm² cross-section ensures efficient current flow, reducing electrical resistance and improving energy dissipation. This unit has an operating factor (SD) of 25%, meaning that it can handle 25% of its rated power continuously without compromising performance.

This braking resistor features a protection class of IP 20, indicating that it is protected against solid objects larger than 12.5 mm, such as tools or wires, but is not sealed against water. This protection level makes it suitable for indoor use in controlled industrial environments where the resistor is shielded from direct exposure to dust or moisture. This unit is suited for an operating temperature range of 0°C to 40°C, ensuring stable performance in typical industrial environments. However, for environments outside this range, additional cooling or environmental controls may be necessary.
