The Schneider Electric VW3A7263 is a line filter module (LFM) rated for 220 kW at 500-690 VAC, designed as a component of the Active Front End (AFE) system for Altivar drives. It handles a line current of 185 A at 50 °C and dissipates 360 W of thermal losses via natural convection — no fan to fail, but the enclosure must allow free airflow around the 730 × 290 × 370 mm (H×W×D) built-in unit. This module is specifically intended for use with one active infeed converter (AIC) model VW3A7270, VW3A7271, or VW3A7272, and it also provides 24 VDC control electronics and fan power for the AIC plus up to four inverters of the same power class operating on 500-690 VAC.
The VW3A7263 is classified as Obsolete by Schneider Electric.
The 500-690 VAC ±10% supply voltage range covers standard 400 V-class and 690 V-class industrial networks in 50/60 Hz three-phase systems. The 185 A line current at 50 °C is the thermal limit under natural convection; above 45 °C ambient, derate the current by 2% per °C up to 60 °C. At altitudes above 1000 m, derate current 1% per 100 m to 2400 m max. Pollution degree 2 per EN/IEC 61800-5-1 is the standard for industrial control cabinets where non-conductive pollution occurs but occasional condensation is expected. Electrical connections use M10 bus bars for the power terminals (95 mm² for PE, 185 mm² for line) and a 2.5 mm² terminal for the control signals. Shock resistance is 7 gn for 11 ms per EN/IEC 60068-2-27, and vibration resistance is 1.5 mm at 3-10 Hz and 0.6 gn at 10-200 Hz per IEC 60068-2-6, which covers normal industrial machinery vibration.
Storage temperature range is -25 to 70 °C; operating range is -10 to 45 °C (with derating to 60 °C). Relative humidity tolerance is 0-95% non-condensing. Environmental classification per EN/IEC 60721-3-3 is 3K3 (temperature and humidity), 3C2 (chemical gases), and 3S2 (mechanical particles) — suitable for most factory-floor conditions without aggressive atmospheres.
