Product Description:
The RZW02.1-055-015 is a compact and energy-efficient braking resistor designed for automation systems. Its low-inductance construction ensures smooth, reliable braking without voltage spikes. The resistor operates by safely converting the excess electrical energy that is generated during deceleration into heat then dissipating it safely. This helps to safeguard the connected drive components by maintaining stable voltage even during fast braking conditions. This resistor model features a fixed design and comes enclosed in a steel enclosure for mechanical stability and environmental protection. The fixed design means that the resistance value is constant and precisely engineered for predictable braking behavior, ensures long-term reliability.
The RZW02.1-055-015 is rated for a switching duration of 15%, allowing it to handle full load operation for 15% of each duty cycle. This makes the resistor ideal for applications that feature short, repeated braking intervals rather than continuous energy dissipation. The 15% SD rating ensures that the unit remains within safe thermal limits, preventing overheating while still delivering reliable performance during each braking phase. This resistor offers a continuous power capacity of 55kW, allowing it to efficiently handle substantial braking energy in medium-to-heavy industrial drive systems.
The RZW02.1-055-015 supports a minimum connectable resistance of 5 Ohms, the lowest safe resistance value that can be connected to the resistor. This threshold helps ensure that the braking circuit operates within the designed electrical limits, preventing excessive power dissipation that could lead to overheating or component stress. For reliable operation, this resistor is protected against the ingress of solid objects larger than 12.5mm, such as tools or fingers, but not against liquids. This makes it suitable for use in enclosed, dry environments like control panels or machine cabinets.
