Schneider Electric VW3A7730 Braking resistor 1 pc(s)
Braking resistor, for ATV930U07M3, ATV930U07N4-U40N4, ATV950U07N4-U40N4, ATV950U07N4E-U40N4E converters. Reference values for a light braking cycle. Output VA 0.1 kW, protection class IP20, resistance 100 ?at 20 °C. Supply voltage 200-240 V or 380-480 V 50/60 Hz. Load factor for resistors The value of the average power, which can be derived from the resistance in the housing at 50°C. Determined for a load factor during braking that corresponds to the majority of common applications. Standard overload 0.8 s Brakes with a braking torque of 1.2 Tn for a cycle of 40 s. High overload 0.8 s braking with a braking torque of 1.5 Tn for a cycle of 40 s. Required number per converter 1. Braking resistors allow Altivar process frequency converters to operate during braking until standstill by deriving the braking energy. They enable maximum transient braking torque. Braking resistors are designed for a defined cycle. Depending on your own applications and cycles, you can use these resistors or define a new value. Braking resistors for light braking cycles for machines with cycles and mass inertia. The braking power is limited to 1.5 Tn for 0.8 s every 40 s. Braking resistors for medium braking cycles for machines with high mass moment of inertia and conveyor systems. The braking power is limited to 1.35 Tn for 4 s every 40 s.This text is machine translated.
