The 3VA1110-4FF42-0AA0: Continuous current rating holds at 100 A up to 50 °C, then derates linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power loss is 25 W.
Four-pole width at 101.6 mm is standard for this class; verify DIN-rail or screw-mount spacing against the existing panel cutout. N-conductor protection is set at 50% of the phase rating. An optional motor drive is available for remote operation.
130 mm high, 101.6 mm wide, 70 mm deep.
