Schneider Electric VW3A7755 8Ohm 25kW IP23 braking resistor

Braking resistor, for ATV930D15M3, ATV930D55N4, ATV950D55N4, ATV950D55N4E drives. Reference values for a heavy braking cycle (lifting applications). Power VA 25 kW, protection class IP23, resistance 8 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 that can be dissipated from the resistor into the housing at 50 °C. Determined for a load factor during braking that corresponds to the majority of common applications. High overload 54 s braking at a braking torque of 1 Tn and 6 s braking at a braking torque of 1.65 Tn for a cycle of 120 s. Required number per inverter 1.
