Schneider Electric Braking resistor, 1.4 ohm, 29 kW, IP23 VW3A7757

Brake resistor for inverter ATV930D55M3C - D75M3C. Reference values for a heavy braking cycle (lifting applications). Power 29 kW, protection class IP23, resistance 1.4 Ω 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 typical applications. High overload: 54 seconds of braking at a braking torque of 1 ton and 6 seconds of braking at a braking torque of 1.65 tons for a cycle of 120 seconds. Required number per inverter: 1.
